PART I

ITEM 1. BUSINESS.

Company Overview

Altera Corporation is a global semiconductor company that designs and sells a variety of products, including:

Programmable logic devices (“PLDs”), which consist of field-programmable gate arrays (“FPGAs”), including those referred to as systems-on-chip FPGAs ("SoC FPGAs") which incorporate hard embedded processor cores, and complex programmable logic devices (“CPLDs”). FPGAs and CPLDs are standard semiconductor integrated circuits, or chips, that our customers program to perform desired logic and processing functions in their electronic systems.

Highly integrated power devices, known as power system-on-chip devices ("PowerSoCs"), which simplify and drive the miniaturization of power circuitry typically found in the electronic systems of our PLD customers.

Pre-defined design building blocks, known as intellectual property (“IP”) cores, which can be licensed by customers to add standard functions to their PLD designs.

Proprietary development software, which operates on personal computers and engineering workstations, is used by customers to develop, compile, and verify their designs, and then program their designs into our PLDs.

Our goal is to be the leading supplier of programmable semiconductors and related products that enable electronic systems companies to rapidly and cost-effectively innovate and differentiate in their markets. We serve over 12,100 customers within the Telecom and Wireless, Industrial Automation, Military and Automotive, Networking, Computer and Storage, and Other vertical markets.

Altera was founded in 1983. Our headquarters are located at 101 Innovation Drive, San Jose, California 95134, and our website is www.altera.com. Our common stock trades on the NASDAQ Global Select Market under the symbol ALTR.

How PLDs are used in Electronic Systems

Our customers design electronic systems that typically use three types of digital integrated circuits:

Processors, which include microprocessors, microcontrollers, graphics processors, and digital signal processors, control central computing tasks and signal processing.

Memory stores programming instructions and data.

Logic manages the interchange and manipulation of digital signals within a system.

System designers typically use standard architectures to meet their processor and memory needs. System differentiation may be realized through the development of software algorithms that are executed by a processor, as well as specialized hardware that has been designed into the logic circuits.

Most applications use one or more of the following types of semiconductor devices to implement designs:

Application-specific integrated circuits ("ASICs") - Often referred to as standard cells, ASICs are manufactured with custom designs created by the customer. An ASIC is developed with custom logic targeted to a specific end application. An ASIC may also include licensed microprocessor and memory cores which may allow limited software programmability through the modification of software algorithms that are executed on the microprocessor. Each ASIC has a targeted function used by a single customer in a single application.

Application-specific standard products (“ASSPs”) - ASSPs are standard devices that utilize a development methodology similar to that of an ASIC. However, in contrast to an ASIC, which is built for a single customer, an ASSP is built for a specific type of application targeted to a small number of customers. ASSPs are sometimes described as ASICs developed for multiple customers.

PLDs - Unlike ASICs and ASSPs, PLDs are standard products that can be customized for a wide range of applications. While originally developed for logic implementation, more recent PLD architectures have evolved to include various memory, digital signal processing ("DSP"), embedded microprocessor and even analog functionality. PLDs are typically sold to hundreds or thousands of customers. PLD flexibility offers many advantages including simple design changes, shorter design cycles, and lower development costs.

PLDs vs. ASICs and ASSPs

In a broad sense, PLDs, ASICs and ASSPs compete with each other because they may be used in the same types of applications in electronic systems. However, differences in cost, performance, density, flexibility, ease-of-use, and time-to-market dictate how much they directly compete for particular applications. The table below summarizes key characteristics of ASICs, ASSPs, and PLDs.



	ASIC	ASSP	PLD
CUSTOMIZABLE	Yes, by chip fabrication facility	No	Yes, by end user
ERASABILITY/REPROGRAMMABILITY	No	No	Yes
RELATIVE TIME TO MARKET	Slow	Immediate	Fast
RELATIVE UNIT COST	Low	Moderate	Moderate to high
CUSTOMER'S DEVELOPMENT COST	High	Low	Moderate
FIELD UPGRADABILITY	No	No	Yes

In contrast to ASICs, PLD designs are electronically programmed directly into the PLD. This means that the PLD is fully functional and verified when the design is completed, avoiding the lengthy and complex cycles required to verify and fabricate ASICs. User programmability allows PLD customers to test and revise their designs quickly and with lower development cost. In addition to these ease-of-use and time-to-market advantages, PLDs can be upgraded in the field, which allows customers to modify the PLD design after the electronic system has been shipped.

Customers use ASSPs when they need specific fixed functions with little differentiation, for example when implementing certain electronic industry standards. However, ASSPs have highly targeted functionality, which limits the range of applications they can address. In contrast to ASSPs, PLD flexibility allows customers to define functionality to suit their needs, rather than restrict their system architecture based on ASSP manufacturer specifications. Furthermore, PLD designers can add IP design blocks to execute standardized functions otherwise performed by ASSPs.

These design flexibility advantages historically resulted in a relatively high unit cost for PLDs. Programmability required a larger die size, which typically translated into a higher per-unit cost when compared with ASICs or ASSPs manufactured using the same process technology. As a result, unit volume for PLDs was typically lower than for ASICs or ASSPs. In addition to driving higher cost, the larger die area caused by programmable circuitry also had disadvantages in terms of performance and power consumption

for PLDs when compared with ASICs or ASSPs manufactured using the same process technology. Over the past decade, however, certain trends have begun favoring PLDs over ASICs and ASSPs in an increasing number of applications.

Trends Favoring PLDs over ASICs and ASSPs: Semiconductor Economics and Silicon Convergence

As chip manufacturing becomes more advanced, the total cost of chip development increases, significantly increasing the revenue required to justify the development cost. Because an ASIC or ASSP revenue opportunity is limited to a single design or specific application, the revenue requirement to justify its increasingly high cost of development may not be achievable. As a means of reducing cost, some ASIC and ASSP suppliers choose to use non-leading-edge process technology for new designs. In contrast to ASIC and ASSP suppliers, PLD suppliers may aggregate revenue for a given PLD from a vast number of designs across market segments, thus allowing PLD suppliers to more readily absorb the increasing development cost associated with advanced process technology. As a result, leading PLD suppliers have continued to utilize the most advanced process technology. The figure below shows Altera's estimate of the growing "process technology gap" for new designs between PLDs and the ASIC alternative. (Note: Most common ASIC process node utilizes research from Gartner, Inc.).

For our most current designs, PLD process technology is typically two or more generations more advanced than the most common ASIC and ASSP process technology. Consequently, the die size difference between PLDs versus ASICs and ASSPs has decreased in recent years. In many cases, it is no longer technologically feasible for ASIC and ASSP suppliers to continue to use old process generations for technically advanced systems, and, at the same time, it is not economically feasible for them to use new generations of technology for low and mid-range volume applications. We believe this has increased our opportunity to displace ASICs and ASSPs.

In order to compete effectively in their end markets, developers of electronic systems continuously seek ways to improve system performance, lower power consumption and reduce system cost. In reaction to the needs of system developers, state-of-the-art semiconductor design has moved increasingly toward silicon convergence, or the combination of multiple semiconductor types, including processors, analog devices, and memories, into a single device. Silicon convergence reduces the number of devices in a single system, minimizes the delay caused by chip-to-chip connectivity, and lessens the amount of input/ output ("I/O") switching power consumed. Silicon convergence is facilitated through the licensing of standard architectures for microprocessors as well as IP cores. Once licensed, the microprocessors and IP cores may be combined with additional circuitry such as memory cores and custom logic into a single integrated circuit.

We believe that innovations in PLD architecture and PLD development tools have also contributed to the increasing use of PLDs over ASICs and ASSPs. Newer PLD capabilities, such as high speed transceivers, embedded DSP and embedded microprocessors are helping current PLD architectures become more "silicon convergence-friendly" when compared to previous PLD architectures, thereby allowing electronics engineers to increasingly use PLDs to meet complex system requirements for performance, power consumption and cost. Licensed cores for microprocessors as well as a variety of IP are commercially available but licensed cores for PLDs are not generally available. We believe that customers will increasingly turn to PLD suppliers for not only logic functionality, but also for system integration, in both prototyping and production quantities.

FPGAs as Efficient Coprocessors

One of the most important semiconductor segments is the processor category. Processors comprise standard architectures that may be tailored towards particular end markets or core functions such as desktop computing, network processing, graphics processing, and digital signal processing. Software developers create software algorithms that run on the chosen processor platform in order to differentiate their electronic system.

The power consumption and speed of a developed software algorithm will differ depending on the processor architecture as well as the type of software algorithm. FPGA architectures can provide a much greater level of parallel processing by offering nearly one million small but flexible cores. FPGAs have been found to implement many algorithms at greater than an order of magnitude higher performance per watt than standard processor architectures. Recent advances in design software by FPGA suppliers have made the advantages of FPGAs more accessible to software developers familiar with C-code based development methodologies. Fundamental device architectural advantages and innovations in design software have led to the increasing use of FPGAs as efficient coprocessors, offloading the main processor and allowing FPGA suppliers to capture additional system content traditionally implemented in microprocessors (MPUs/ CPUs), graphics processors (GPUs), digital signal processors (DSPs) and microcontrollers (MCUs). Furthermore, FPGAs as efficient coprocessors, especially in data center-related applications within our Computer sub-vertical market, are providing PLD suppliers an additional growth opportunity beyond the traditional displacement of ASICs and ASSPs.

PLD Market Overview

Based on publicly available data and information derived from Gartner, Inc., an independent research firm, we estimate that the PLD market was approximately $4.5 billion in 2013. We also estimate that the combined portion of the ASIC and ASSP markets in 2013 that was accessible to PLDs was approximately $48.1 billion which represents significant PLD growth potential.

In addition to the accessible portion of the ASIC and ASSP market of $48.1 billion in 2013, we believe our recent and future embedded processor solutions, including recently introduced SoC FPGAs, which integrate ARM^®-based hard processor systems, offer an additional accessible market of approximately $8.4 billion. This additional market opportunity offers significant overlap with the end equipment markets we currently serve.

The figure below shows the main types of semiconductors that PLDs may displace in future electronic systems, mapped against a pie chart of our 2013 revenue by vertical market.

Within the PLD market, there are two distinct sub-segments, CPLDs and FPGAs, which comprise the majority of revenues but, due to product differences, usually do not compete directly for the same customer designs. The FPGA market has outgrown the CPLD market over the last several years. FPGAs now account for approximately 85% of total PLD sales and are expected to continue to be the fastest growing segment of the PLD market.

Within the FPGA market, there are three main product types: high-end FPGAs, mid-range FPGAs and low-end FPGAs. The high-end FPGA category has historically represented a majority of total FPGA revenue. Increasing our FPGA market share and the further success of our new FPGA product families is important to our long-term growth and profitability. Since the initial introduction of our Stratix and Cyclone FPGA families in 2002, we have introduced several more FPGA families in the Stratix, Cyclone and Arria series of products, including our SoC devices that incorporate hard embedded processors.

Based on publicly available data and with information derived from Gartner, Inc., we estimate that our market share has increased or decreased over the last five years as follows:



Market Share	2008		2013

PLD⁽¹⁾	36	%	38	%
FPGA	34	%	37	%
CPLD	40	%	36	%


(1)	Includes revenue from FPGA and CPLD sub-segments as well other products including development software, intellectual property, PowerSoCs, and HardCopy^® devices

Competition

We compete with other PLD vendors to displace other semiconductor alternatives and for market share within the PLD market. Competition between PLD vendors is most intense in the “design-win” phase of the customer's design, when customers select products for use in the customer's electronic system. Customers often prefer to use the same PLD vendor in successive product generations. This "incumbency advantage" is driven by a customer's investment in building expertise with the PLD vendor's

software and the re-use of portions of a design from prior generations. In addition, because each PLD vendor's products are proprietary, the cost to switch PLDs after a system has been designed and prototyped can be high. Therefore, a design win can provide the PLD vendor with a profitable revenue stream through the life of the customer's program.

The figure below illustrates our estimated life cycle for our devices. From the time a design win is secured, it can be two or more years before a customer starts volume production of its system. Typically, the customer selects the PLD vendor relatively early in a customer's design process, but it may take several years to complete system design, build prototypes, sample the marketplace for customer acceptance, make modifications and manufacture in volume. Thus, there is a delay between developing a competitive advantage and experiencing a shift in the PLD market, meaning that market share is a lagging indicator of relative competitive strength.

The principal competitive factors in the PLD market include:


•	Technical innovation


•	Device performance, power consumption, and features


•	Capability and productivity of software development tools


•	Availability, quality and capability of IP cores


•	Pricing and availability


•	Quality and reliability


•	Technical service and customer support


•	Manufacturing and operational competence


•	Customer familiarity with existing vendors and entrenched products

We believe that we compete favorably with respect to these factors and that our proprietary and tailored device architectures, embedded processor solutions, and installed base of software development systems provide an additional competitive advantage. Due to unique architectural innovation and advanced technologies, our new product families provide greater functionality and lower power consumption at a lower price for any given logic density compared with their predecessors. Newer product features such as hard embedded processors, multi-gigabit transceivers and floating point DSP blocks, as well as software advancements such as an efficient C-code software programming environment through support for OpenCL, have enhanced our design-win value over time.

We also believe that our new product families offer capabilities that allow us to compete more favorably against ASICs and ASSPs, as well as against other types of chips such as microcontrollers, microprocessors, graphics processors, and digital signal processors. Designers can add some of the functionality of these other chips to PLDs using pre-built and pre-verified IP cores. An IP core is typically offered in either a “hard” or “soft” form. Altera, at the time of chip development for our PLDs, can embed a hard IP core into the actual circuitry of the PLD. A soft IP core is a licensed design file that our customers incorporate into their design and program onto the PLD. By incorporating more functionality and logic capacity on a programmable chip while providing the

necessary design tools and IP cores to design a reliable system, we believe we can enhance the advantages of PLDs over competing solutions.

Not only do we compete with other PLD vendors such as Lattice Semiconductor Corporation, Microsemi Corporation, and Xilinx Inc., but we may also encounter a variety of other semiconductor vendors during a given customer engagement. Other semiconductor companies with whom we may compete include Analog Devices Inc., Applied Micro Circuits Corporation, Avago Technologies, Broadcom Corporation, Freescale Semiconductor Inc., International Business Machines Corporation, Intel Corporation ("Intel"), Linear Technology Corporation, Marvell Technology Group, Ltd., Maxim Integrated Products Inc., Microchip Technology Inc., Nvidia Corporation, PMC-Sierra Inc., Renesas Electronics Corporation, ST Microelectronics, Texas Instruments Inc., Toshiba Semiconductor Company and Vitesse Semiconductor Corporation.

Customers integrate IP cores in their PLD designs with our proprietary development software. Soft IP cores available for use in our devices include our Nios^® series of embedded processors, our portfolio of MegaCore^® functions that we license to our customers, and our Altera Megafunction Partners Program ("AMPP^SM") cores, which are pre-verified by us and licensed to our customers by third parties.

With IP cores, system designers can focus more time and energy on improving and differentiating the unique aspects of their system designs, rather than spending time designing common off-the-shelf functions. IP cores are essential to providing solutions with higher levels of integration and faster time to market. Today, we offer a broad range of soft IP cores for DSP algorithms, bus interfaces, memory controllers, telecommunications, data communications, microprocessors, and peripherals. Before licensing a

soft IP core, customers can download an encrypted soft IP core from our website and verify that it works in their own system designs. While licensing soft IP cores represents a small portion of our net sales, we believe a broad product offering in this area is necessary to compete with ASIC and ASSP vendors as well as other PLD vendors.

Development Tools

To enhance engineering productivity, customers use our proprietary development tools, consisting primarily of the Quartus^® II software, for design entry, design compilation, design verification, and device programming.

Our development tools provide efficient support of both hardware and software programming environments. PLD users have typically implemented their designs within a hardware programming environment in which a hardware description language has been employed. With the increasing appeal of FPGAs as efficient coprocessors and the continued introduction of advanced SoC FPGAs that incorporate hard embedded processors, there has been an increasing demand from software developers who are more accustomed to a software programming environment in which a C-code based programming language is utilized. Software developers who develop in a C-code based programming language may utilize the OpenCL standard.

Designers can use our development tools on a variety of computing platforms, including Microsoft Windows, UNIX (including Solaris and HP-UX), and Linux operating environments, with built-in interfaces to industry-standard EDA tools offered by Cadence Design Systems, Inc., Mentor Graphics Corporation, Synopsys, Inc. and others.

Like IP cores, our development tools generate less than 10% of our net sales, but are a critical and necessary element of our product portfolio because they are used to program our devices and can drive our success in competing for design wins against PLD, ASIC and ASSP vendors.

Research and Development

Our research and development activities focus primarily on PLDs, PowerSoCs, IP cores, and development software. We develop these related products in parallel to provide comprehensive design support to customers. As a result of our research and development efforts, we introduced a number of new families in recent years, including the Stratix V, Stratix IV, Cyclone V, Cyclone IV, Arria V, and MAX V device families, as well as major enhancements to our IP core offerings and the Quartus II development platform. Our MAX and Arria 10 Series products are planned for initial shipment in 2014.

Our research and development costs, which are charged to expense as incurred, were $385.2 million in 2013, $359.6 million in 2012 and $324.2 million in 2011.

Patents, Trademarks, and Licenses

We rely on intellectual property laws, including patent, copyright, trademark, and trade secret laws, to establish and maintain our proprietary rights in products and technology. Activities include:


•	Patents - As of December 31, 2013, we owned more than 3,000 United States patents and 490 foreign patents. We also had more than 1,200 patent applications pending worldwide.


•	Trademarks - We use, register and apply to register certain trademarks and service marks in the United States and foreign countries.


•	Product registrations - We file registrations in the United States under the Semiconductor Chip Protection Act to protect our chip designs.


•	When appropriate, we file lawsuits to protect our intellectual property rights.

We have also licensed technology that allows us to design, manufacture and sell products using certain intellectual property owned by others.

Marketing and Sales

We market our products worldwide through a network of distributors, independent sales representatives and direct sales personnel.

Altera Distributors

In all of the major geographic markets that we serve, we work with distributors to provide demand creation for the broad customer base and order-fulfillment services for most of our customers. These distributors are franchised by component manufacturers to sell a wide variety of products to many customers, and they may sell competing products or solutions. We have contracts with our distributors that can be terminated by either party upon notice.

All of our distributors stock inventory of our products. Distributors purchase products from us at a set distributor cost denominated in U.S. dollars. Title and risk of loss transfer upon shipment from our stocking locations, which are located in the Asia Pacific region at the independent subcontractors that we employ for test and assembly services or at our warehouse in San Jose. When products are shipped to a distributor, we generally defer revenue on the sale until the distributor sells the products in accordance with our revenue recognition policy. Consequently, the deferred revenue and the corresponding deferred cost of sales are recorded as a current liability under the caption Deferred income and allowances on sales to distributors. All payments to us are denominated in U.S. dollars. For a detailed discussion of our revenue recognition policy, see Note 2: Significant Accounting Policies - Revenue Recognition to our consolidated financial statements.

Our sales cycle begins with a “design-win” phase, which can be lengthy, is uncertain and often requires the ongoing participation of sales, engineering and managerial personnel. Once customer demand has been created and a design is ready to move to prototyping or production, the order-fulfillment process begins. Customer orders are primarily processed and fulfilled by a local distributor. For these orders, our distributors are the legal sellers of the products and therefore bear all risks related to the ownership and sale of the products, including credit loss, inventory shrinkage and theft and foreign currency fluctuations. For certain arrangements, Altera drop ships products to fulfill orders processed through our primary distributor.

Our distributors periodically return certain amounts of unsold product and receive price concessions for unsold product if we reduce prices. For high-volume or competitive situations, we often provide price concessions to our distributors. A customer purchasing a small quantity of product from a distributor usually pays list price. However, a customer using our products in volume production, purchasing thousands or even hundreds of thousands of units, will often negotiate a substantial price discount from the distributor. Under these circumstances, the distributor will often negotiate and receive a price concession from Altera. These price concessions are negotiated in U.S. dollars. Average aggregate price concessions typically range from 70% to 85% of our list price on an annual basis, depending upon the composition of our sales, volume and factors associated with timing of shipments to distributors or payment of price concessions. This is a standard practice in the semiconductor industry, and we generally provide some level of price concession to every distributor.

Our net sales are the sum of our own direct sales to original equipment manufacturers, or OEMs, plus our distributors' resale of Altera products. For 2013, 2012 and 2011, worldwide sales through distributors for subsequent resale to OEMs or their subcontract manufacturers accounted for 77%, 71% and 73%, respectively, of our net sales. Arrow Electronics, Inc. including its affiliates (“Arrow”), our largest distributor, accounted for 41% of our net sales in 2013, 40% in 2012 and 39% in 2011. Our second largest distributor, Macnica, Inc. including its affiliates (“Macnica”), accounted for 23% of our net sales in 2013, 21% in 2012 and 21% in 2011. No other distributor accounted for more than 10% of our net sales in 2013, 2012 or 2011.

Altera Sales, Marketing, and Customer Support

Altera has a dedicated global sales and marketing organization to create customer demand and manage our network of distributors and independent sales representatives. We focus our direct demand creation efforts on a limited number of key accounts, and provide technical, business and marketing support to distributors and independent sales representatives. Independent sales representatives, who are mostly located in North America and in select European countries, create demand and provide customer support in a defined territory and often with a defined set of customers. They do not stock inventory or fulfill orders. All of our contracts with independent sales representatives can be terminated by either party upon notice.

Customer support and service are important to selling and marketing our products. We provide several levels of technical support, including application assistance, design services, and customer training. We also publish data sheets and application notes, conduct technical seminars and provide design assistance to customers via the Internet and electronic links.

We have domestic sales offices in numerous major metropolitan areas throughout the United States, and we maintain international sales support offices in Bangalore, Beijing, Cork, Chengdu, Helsinki, Hong Kong, London, Munich, Osaka, Ottawa, Paris, Seoul, Shanghai, Shenzhen, Singapore, Stockholm, Taipei, Tokyo, Toronto and Turin.

Huawei Technologies Co., Ltd. (“Huawei”), an OEM, individually accounted for 11% of net sales in 2013, 16% of net sales in 2012 and 13% of net sales in 2011. No other individual OEM accounted for more than 10% of net sales in 2013, 2012 or 2011.

International Sales

Sales outside of the U.S. and Canada constituted 82% of net sales in 2013, 82% of net sales in 2012 and 81% of net sales in 2011. Sales to Japan accounted for 16% of net sales in 2013, 14% of net sales in 2012 and 15% of net sales in 2011. Sales to China accounted for 29% of net sales in 2013, and 33% of net sales in each of 2012 and 2011. Except for the United States, China and Japan, no other country accounted for sales in excess of 10% of net sales during 2013, 2012 or 2011. For a detailed description of our sales by geographic region, see Item 7: Results of Operations - Sales by Geography, and Note 17: Segment and Geographic Information to our consolidated financial statements.

Backlog

Our backlog consists of distributor orders, as well as certain OEM orders, that are for delivery within the next three months. Our backlog of orders as of December 31, 2013 was approximately $1.7 billion, and was consistent with our backlog as of December 31, 2012.

Historically, backlog is a poor predictor of future sales or customer demand for the following reasons:


•	While our backlog increases during periods of high demand and supply constraints, purchasers may, in most cases, cancel product orders up to 30 days before the scheduled delivery date without incurring significant cancellation penalties.


•	Our backlog is valued at list price, which in most cases is substantially higher than the price ultimately recognized as revenue.

Manufacturing

Wafer Supply

Die, cut from silicon wafers, are the essential components of all our devices and comprise a significant portion of the total device cost. Our manufacturing strategy is known as a “fabless” business model since we purchase our silicon wafers from independent semiconductor foundries instead of manufacturing them ourselves. This strategy allows us to take advantage of these suppliers' economies of scale and gives us direct and timely access to advanced process technology. Currently, we purchase our silicon wafers from Taiwan Semiconductor Manufacturing Company (“TSMC”), an independent semiconductor foundry. We have no formalized long-term supply or allocation commitments from TSMC. In 2013 we announced a new foundry relationship with Intel, which gives us access to Intel's 14 nm FinFET technology, and we may establish additional foundry relationships as they become economically beneficial or technically necessary.

Testing and Assembly

After wafer manufacturing is completed, each silicon wafer is tested using a variety of test and handling equipment that is owned by us and consigned to our partners. The vast majority of our silicon wafer testing is performed at TSMC.

The wafers are then shipped to various assembly suppliers in Asia, where they are sorted into good die and encapsulated in packages. We use a number of independent assembly suppliers to take advantage of their economies of scale and supply flexibility, and to give us direct and timely access to advanced packaging technology. We purchase almost all of our assembly services from Amkor Electronics, Inc. (“Amkor”) in Korea and the Philippines, and Advanced Semiconductor Engineering, Inc. (“ASE”) in Malaysia and Taiwan.

Following assembly, each packaged unit completes final testing, marking and inspection before being packaged for storage as finished goods. We also use Amkor and ASE for almost all of our final test and back-end operation services. These partners perform final testing using our proprietary test software operating on hardware that is consigned to or owned by our suppliers.

The majority of our inventory, including finished goods, is warehoused in Asia at our subcontract test and assembly partners. These suppliers also ship our products to OEMs and distributors.

ITEM 1A. RISK FACTORS.

The following risk factors, among others that are not presently known or that we currently believe unimportant, could affect our future results and could cause our actual results to differ materially from those expressed in our forward-looking statements. Before you decide to buy, hold, or sell our common stock, you should carefully consider these risks, in addition to the other information contained in this report. Our business, financial condition, and operations results could be seriously harmed if any of the events described here actually occurs. In that situation, the market price for our common stock could decline, and you may lose all or part of your investment.

Our financial results are affected by general economic conditions and the highly cyclical nature of the semiconductor industry.

Semiconductor companies, such as Altera, experience significant fluctuations in sales and profitability. The semiconductor industry has experienced economic downturns and business contractions from time to time, which can be severe and prolonged. The fluctuations follow the turns of the global economy and in a downturn can result in significant reductions in product demand and excess customer inventories. Global economic weakness or cyclical downturns have previously resulted from periods of economic recession, reduced access to credit markets, weakening or strengthening of the U.S. dollar relative to other currencies, weak end-user demand, excess industry capacity or general reductions in inventory levels by customers. It is difficult for our customers, our vendors and us to accurately forecast and plan future business activities in today's global economy.

Our ability to predict the quantity and type of products our customers will need in the future is limited because our customers face volatile pricing and unpredictable demand for their own products and are increasingly focused on cash preservation and tighter inventory management. These factors could affect the timing of customer orders and the overall level of demand for our products. Because it is extremely difficult to forecast the success or timing of a customer's product, and because our end markets are highly fragmented (we have over 12,100 PLD customers), our ability to forecast end customer demand is limited. If we overestimate customer demand, we may allocate resources to manufacturing products that we may not be able to sell as quickly as estimated, if at all. As a result we could hold excess or obsolete inventory, which would reduce our profit margins and adversely affect our financial results.

The volatility and disruption of the capital and credit markets and adverse changes in the global economy may negatively impact our customers' business and their ability to access financing, which could adversely affect demand for our products. Our operating cash flows are highly dependent on the continued collection of receivables and our ability to sell our products. Declines in overall economic conditions could lead to deterioration in the quality of our receivables. In addition to reductions in sales and elevated risk associated with the collection of receivables, our profitability and cash flows may suffer during downturns because we may not be able to reduce costs at the same rate as our sales decline.

As further described below, we depend entirely on independent subcontractors to supply us with finished silicon wafers and to assemble, test and ship our semiconductor products. Uncertainties in the capital and credit market may adversely affect the ability of our suppliers to obtain financing for operations. If our subcontractors' capital structures weaken, they may fail to satisfy our demand and our business could be materially disrupted.

If global economic and market conditions remain uncertain or persist, spread or deteriorate further, we could experience a material impact on our business, financial condition, results of operations or cash flows.

Our gross margins are subject to fluctuations due to many factors.

Our gross margins may fluctuate due to many factors, including:


•	Geographic and vertical market pricing mix


•	Changes in the mix of our prototyping and production-based business


•	Competitive pricing dynamics and customer mix


•	Various manufacturing cost variables including product yields, wafer prices, package and assembly costs, provisions for excess and obsolete inventory and absorption of manufacturing overhead

Our ongoing efforts to manage these factors may not be successful, which could ultimately lead to a reduction in our gross margins.

Our failure to compete successfully in the highly competitive semiconductor industry would adversely affect our financial results and business prospects.

The semiconductor industry, including the PLD market, is intensely competitive. Our ability to compete successfully in the semiconductor industry depends on our ability to provide our customers with solutions providing greater value than those offered by competing programmable logic vendors, such as Xilinx and Lattice, and other semiconductor companies that indirectly compete with us. Because we develop PLDs for applications that are presently served by ASIC, ASSP, FPGA, CPLD, DSP, and microprocessor/microcontroller vendors, we compete against these vendors. From time to time, we have had customers convert high-volume designs to ASICs. To the extent that our efforts to compete are not successful, our financial condition and results of operations could be materially adversely affected. Other competitors include manufacturers of:


•	high-density programmable logic products characterized by FPGA-type architectures


•	high-volume and low-cost FPGAs as programmable replacements for ASICs and ASSPs


•	ASICs and ASSPs with incremental amounts of embedded programmable logic


•	high-speed, low-density CPLDs


•	Microprocessor products


•	PowerSoCs


•	high-performance DSP devices


•	products with embedded multi-gigabit transceivers


•	other new or emerging programmable logic products

Many of these competitors have substantially more financial, technical and marketing resources than we do and have well-established market positions and solutions that have proven technically feasible and economically competitive over several decades. We may be unable to displace these vendors in the targeted applications and densities. Several companies have introduced products that compete with ours or have announced their intention to sell PLD products. The benefits of programmable logic have attracted a number of competitors to this segment. We recognize that different applications require different programmable technologies, and we are developing architectures, processes and products to meet these varying customer needs. Recognizing the increasing importance of standard software solutions, we have developed common software design tools that support the full range of our IC products. We believe that automation and ease of design are significant competitive factors in this segment.

The highly competitive environment of the semiconductor industry and the high costs associated with manufacturing technologies and developing marketable products have resulted in significant consolidation in the industry and are likely to lead to further consolidation. We may become a target for a company looking to improve its competitive position. Such an occurrence may take place at any time with consequences that may not be predictable and that could have a materially adverse effect on our results of operations and financial condition.

We may pursue acquisitions and investments that may disrupt our business if not successfully integrated and could potentially harm our operating results.

We have made and will continue to consider making strategic business investments, alliances and acquisitions that we consider necessary or desirable to gain access to key technologies that we believe will complement our existing technical capabilities and support our business model objectives. Acquisitions, alliances and investments involve risks and uncertainties that may negatively impact our future financial performance. These risks include difficulty in combining the technology, products, operations or workforce of the acquired business with our business and failure to successfully further develop the acquired technology. If integration of our acquired businesses is not successful, we may not realize the anticipated financial or strategic benefits of an acquisition or suffer other adverse effects that we currently do not foresee.

A downturn in the communications equipment end market could cause a reduction in demand for our products and limit our ability to maintain revenue levels and operating results.

Approximately 41% of our net sales for 2013 was derived from customers participating in the Telecom and Wireless vertical market. In the past, a general weakening in demand for programmable logic products from customers in the communications end market has adversely affected our revenue. Any deterioration in the communications end market or reduction in capital spending to support this end market could lead to a reduction in demand for our products and could adversely affect our revenue and results of operations.

The length of our design-in and sales cycles could affect our ability to forecast future sales.

Our sales depend on our products being designed into end customers' products, and on those products being produced in volume. Our products are very complex, and the time from design-in to volume production ranges from six months to three years or more. From initial product design-in to volume production, many factors can affect the timing and/or volume of our sales. These factors include, but are not limited to, changes in the competitive position of our technology, the competitiveness of our end customers' products in the markets they serve, our customers' financial stability, end customer program delays and cancellations, and our ability to ship products according to customer schedules.

Our business is characterized by a general decline in semiconductor product selling prices that may materially and adversely affect our profitability.

The selling prices of our products have decreased over time. We have offset the selling price decreases by reducing manufacturing costs, improving yields and increasing unit sales. However, our ongoing efforts may not be successful or may not keep pace with the anticipated, continued decline in product selling prices, which could ultimately reduce revenues and gross margins.

Because we depend on international sales for a majority of our total sales, we may be subject to political, economic and other conditions that could increase our operating expenses and disrupt our business.

Our operations outside of the United States are subject to risks that are inherent in conducting business under non-U.S. laws, regulations and customs. During 2013, sales outside of the U.S. and Canada constituted approximately 82% of our net sales, and we expect that international sales will continue to account for a significant portion of our net sales. Risks related to our foreign operations include:


•	Unfavorable economic, market, political and social conditions in a specific country or region


•	Fluctuation in foreign currency exchange rates


•	Increased freight costs


•	Interruptions in air transportation


•	Reduced protection for intellectual property rights in some countries


•	Longer receivable collection periods


•	Natural or man-made disasters in the countries or regions where we sell our products


•	Different labor regulations

We must comply with a variety of foreign laws and we experience risks associated with legislation and regulations for importing and exporting semiconductor products. In the future, the United States or other countries may impose quotas, duties, tariffs, taxes or other charges, restrictions or trade barriers for the import or export of our products.

We rely heavily on distributors to generate a significant portion of our sales and fulfill our customer orders. The failure of our distributors to perform as expected could materially reduce our future sales.

Worldwide sales through distributors accounted for 77% of our net sales during 2013. During 2013, Arrow Electronics, Inc. and its affiliates ("Arrow") accounted for approximately 41% of net sales on a worldwide basis, while our next-largest distributor, Macnica, Inc. and its affiliates (“Macnica”), accounted for approximately 23% of net sales. As of December 31, 2013, accounts receivable from Arrow and Macnica individually accounted for 26% and 55%, respectively, of our total accounts receivable. We rely on many distributors to help us create end customer demand, provide technical support and other value-added services to end customers, fill customer orders and stock our products. Our contracts with our distributors may be terminated by either party upon notice. A significant reduction of effort by a distributor to sell our products or a material change in our relationship with one or more distributors may reduce our access to certain end customers and adversely affect our ability to sell our products.

Our distributors are located all over the world and are of various sizes and financial conditions. Lower sales, lower earnings, debt downgrades, the inability to access capital markets and higher interest rates could potentially affect our distributors' operations.

Our ability to add or replace distributors is limited.

We contract with distributors to perform two primary, yet distinct, functions that are difficult to replace:


•	Distributors provide logistics support, such as order entry, credit, forecasting, inventory management and shipment of product, to end customers. The process of integrating systems to allow for electronic data interchange is complex and can be time consuming.


•	Distributors create demand for our products at the engineering level. This mandates the training of an extended distributor sales force, as well as hiring and training specialized applications engineers skilled in promoting and servicing products at the engineering level.

Our distributors' expertise in the determination and stocking of acceptable inventory levels may not be easily transferable to a new distributor. In addition, a significant reduction of effort by a distributor to sell our products or a material change in our relationship with one or more distributors may reduce our access to certain end customers and adversely affect our ability to sell our products.

As a result, end customers may be hesitant to accept the addition or replacement of a distributor.

We rely on independent foundries to supply us with finished silicon wafers. Independent foundry capacity and the failure to satisfy our demand could materially disrupt our business.

Our silicon wafers are produced by TSMC in its manufacturing facilities located primarily in Taiwan and the U.S and in the future by Intel in the U.S. Silicon wafer production facilities have a fixed capacity that is allocated solely by our vendors and beyond our direct control. We have no formalized long-term supply or allocation commitments from TSMC or Intel. Our operations would be disrupted if either foundry ended its relationship with us and we were unable to arrange a satisfactory and cost-effective alternative to quickly fulfill customer orders.

To ensure continued wafer supply, we may establish other wafer supply sources as these arrangements become economically advantageous or technically necessary. However, only a few foundry vendors have the capability to manufacture our most advanced products. If we engage alternative supply sources, we may encounter start-up difficulties and incur additional costs. In addition, shipments could be significantly delayed while these sources are qualified for volume production.

Furthermore, because we rely on third-party foundry vendors, we have little or no direct control over production costs, delivery schedules and wafer quality. We also face increased exposure to potential misappropriation of our intellectual property.

Wafer shortages and/or increased wafer and assembly material costs could lower our gross margins, reduce our sales or otherwise materially disrupt our business.

If market demand for silicon wafers or assembly material suddenly exceeds market supply, our supply of silicon wafers or assembly material could quickly become limited. A shortage in manufacturing capacity could hinder our ability to meet product demand. Moreover, silicon wafers constitute more than half of our product cost. If we are unable to purchase wafers at favorable prices, our gross margins will be adversely affected.

Product manufacturing is complex, and we may not achieve the necessary yields or product reliability that our business requires.

Manufacturing our products is a highly complex and precise process, requiring production in a tightly controlled environment. We depend not only on sufficient foundry manufacturing capacity and wafer prices, but also on good production yields (the number of good die per wafer) and timely wafer delivery to meet customer demand and maintain profit margins. Wafer production yields depend on a wide variety of factors including the level of contaminants in the manufacturing environment, impurities in the materials used, and the performance of personnel and equipment. As a result, we may experience problems with achieving acceptable production yields and timely delivery from our foundry vendors.

Difficulties in production yields can often occur when we begin new product production, when we transition to new processes or when our wafer suppliers move production of a product from one manufacturing plant to another or manufactures the same product at multiple factories. As a result of manufacturing defects, TSMC has also occasionally scrapped wafers, resulting in longer manufacturing lead times. Further, production throughput times vary considerably among the various factories used by our wafer

suppliers, and we may occasionally experience production delays. These difficulties and delays can potentially cause significantly higher costs and lower product availability.

We depend on independent subcontractors to assemble, test and ship our semiconductor products. The failure of these subcontractors to satisfy our demand could materially disrupt our business.

Because we rely on independent subcontractors to assemble, test and ship our semiconductor products and to provide package piece parts, we cannot directly control our product delivery schedules or quality levels. We depend on sufficient subcontractor assembly and test capacities, both in raw materials and services, to meet the demand for our products. Our future success also depends on the financial viability of our independent subcontractors. If market demand for subcontractor material and services exceeds available supply or if the subcontractors' capital structures weaken, we may experience product shortages, quality assurance problems and/or increased manufacturing costs.

Conditions outside the control of our independent subcontractors and distributors may impact their business operations and thereby adversely interrupt our manufacturing and sales processes.

The economic, market, social and political situations in countries where certain independent subcontractors and distributors are located are unpredictable and could have a significant impact on our business if we were unable to obtain or distribute product in a timely manner. Market and political conditions (including currency fluctuation, terrorism, political strife, war and labor disruption), natural or man-made disasters, adverse changes in tax laws, tariffs, import or export quotas, power and water shortages or interruption in air transportation in areas where our independent subcontractors and distributors are located also could have a severe negative impact on our operating capabilities.

Our failure to define, develop and manufacture technologically advanced products would adversely affect the success and growth of our company.

We operate in a dynamic market characterized by rapid technological change. Our products are manufactured using a highly complex and precise process, requiring production in a tightly controlled environment. Our current product development efforts focus on developing new PLDs, related development software and hardware and advanced semiconductor wafer fabrication processes. Our development efforts may impact the timely introduction of competitive new products or product enhancements. Additionally, we may not be successful in developing new products or using and converting established products to new and more advanced process technologies. For example, our current generation product families, including the Stratix V family, are manufactured on a 28-nanometer process technology, but our next-generation product families will be manufactured on smaller circuit geometries that we have not used before. The use of advanced process technology has technological risks and start-up difficulties that can adversely affect research and development spending, yields, product costs and product delivery timeliness.

Our ability to service our debt obligations requires sufficient cash flow from our future operations.

On October 29, 2013, we issued $600 million aggregate principal amount of 2.50% senior notes (the "2.50% Notes") due in 2018 and $400 million aggregate principal amount of 4.10% senior notes (the "4.10% Notes") due in 2023. In 2012, we issued $500 million aggregate principal amount of 1.75% senior notes (the "1.75% Notes") due in 2017. All three of our senior notes (the "Notes") pay a fixed rate of interest semiannually and we may redeem the Notes, in whole or in part, at any time for cash at the redemption prices described in the indentures. Our debt obligations may make it difficult for us to satisfy our financial obligations, including making scheduled principal and interest payments on the Notes, and may limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, acquisitions or other general business purposes. Our ability to meet our debt service obligations will depend on our future performance, which will be subject to financial, business and other factors affecting our operations, many of which are beyond our control.

Failure of our information technology systems to function properly, or unauthorized access to our systems, could result in significant business disruption.

We rely on information technology ("IT") systems to manage our business. We evaluate our business processes and our IT systems on an ongoing basis and make periodic enhancements to our business processes and the functionality of our IT systems. In connection with these enhancements, we modify our processes and controls to ensure continued reliability and integrity of our business processes and related IT systems. Any delay in the implementation of, or disruption in the transition to, new or enhanced processes, systems or controls could adversely affect our ability to generate accurate financial and management information in a

timely manner. These systems are also susceptible to power and telecommunication disruptions and other system failures. Failure of our IT systems or difficulties in managing them could result in business disruption.

We also may face the risk of unauthorized access to our IT systems through a security breach or attack. We strive to identify and investigate any such security incidents and prevent their recurrence. However, in certain cases, there may be undetected incidents or the impact of identified incidents may not be fully understood. Our business could be significantly disrupted and we could be subject to third party claims in the event of a significant security breach.

Any prolonged disruption to our global communications infrastructure could impair our ability to plan production activity and respond to customer demand.

Demand for our products is highly volatile, especially at the detailed ordering code level. To achieve short delivery lead times and superior levels of customer service while maintaining low levels of inventory, we constantly adjust our manufacturing subcontractors' production schedules. We develop and adjust these schedules based on end-customer demand as communicated by our distributors and based on our inventory levels, manufacturing cycle times, component lead times, and projected production yields. We combine and distribute all of this information electronically over a complex global communications network. Our ability to estimate demand and to adjust our production schedules is highly dependent on this network; we have no manual back-up. A prolonged disruption or service failure in a portion of this network would impair our ability to plan production activity and respond to demand.

Product quality problems could lead to reduced revenue, gross margins and net income.

We produce highly complex hardware and software products that incorporate leading-edge technology. Our pre-shipment testing programs may not detect all defects. Because our product warranties against materials and workmanship defects and non-conformance to our specifications are for varying lengths of time, we have occasionally been required to replace components or refund the purchase price paid due to product defects. If the costs for customer or warranty claims increase significantly compared with our historical experience, our revenue, gross margins and net income may be adversely affected. For example, if we cannot fix a product defect in a timely manner, we may incur product reengineering expenses, increased inventory costs or damage to our reputation, any of which could materially affect our revenue, gross margins and net income.

We may be subject to product liability claims.

Our devices are used in automotive, military, aerospace, avionics, medical equipment and other systems where system failure could cause damage to property or people. We may receive product liability claims if our devices cause system failures. Based on our historical experience, we believe that the risk of exposure to product liability claims is currently low, but could be higher if either the sales volume in these applications or the frequency of system failures caused by our devices increases.

Our business is subject to the risks of earthquakes and other catastrophic events.

Our corporate headquarters in San Jose, California is located near major earthquake faults. Some of our international facilities and those of our key suppliers, including TSMC, which produces our silicon wafers, are also located near major earthquake faults. Any catastrophic event, such as an earthquake or other natural disaster, could make it difficult for Altera and our independent subcontractors to meet product design deadlines, maintain our records, pay our suppliers, or manufacture or ship our products. Any catastrophic event could also affect our customers or potential customers, which could reduce or delay orders and ultimately decrease our revenue.

As we carry only limited insurance coverage, any incurred liability resulting from uncovered claims could adversely affect our financial condition and operating results.

Our insurance policies may not be adequate to fully offset losses from covered incidents, and we do not have coverage for certain losses. We believe our existing insurance coverage is consistent with common practice and economic and availability considerations. If our insurance coverage is inadequate to protect us against unforeseen catastrophic losses, any uncovered losses could adversely affect our financial condition and operating results.

We could be subject to additional income tax liabilities.

A change in our effective tax rate could have a significant adverse impact on our business, and an adverse outcome resulting from examination of our income or other tax returns could adversely affect our results. We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in evaluating and estimating our provision and accruals for these taxes. During the ordinary course of business, there are many transactions for which the ultimate tax determination is uncertain. Our effective tax rates could be adversely affected by earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated in countries where we have higher statutory rates, by losses incurred in jurisdictions for which we are not able to realize the related tax benefit, by changes in foreign currency exchange rates, by entry into new businesses and geographies and changes to our existing businesses, by acquisitions (including integrations) and investments, and by changes in the valuation of our deferred tax assets and liabilities,. In addition, our effective tax rate could be impacted by changes in the relevant tax, accounting and other laws, regulations, administrative practices, principles, and interpretations, including fundamental changes to the tax laws applicable to corporate multinationals. The United States, many countries in the European Union, and a number of other countries are actively considering changes in this regard. We are subject to audits in various jurisdictions, and such jurisdictions may assess additional income tax liabilities against us. Although we believe our tax estimates are reasonable, the final outcome of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. Developments in an audit, litigation, or the relevant laws, regulations, administrative practices, principles, and interpretations could have a material effect on our operating results or cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods.

Compliance with new regulations regarding the use of conflict minerals could limit the supply and increase the cost of certain metals used in manufacturing our products.

Recently there has been increased focus on environmental protection and social responsibility initiatives. Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 requires the SEC to promulgate new disclosure requirements for manufacturers of products containing certain minerals that are mined from the Democratic Republic of Congo and adjoining countries. These “conflict minerals” are commonly found in metals used in the manufacture of semiconductors. The new disclosure rules were effective in 2013 and require us to file a form SD with the Securities and Exchange Commission by May 31, 2014. The implementation of these new regulations may limit the sourcing and availability of some of the metals used in the manufacture of our products. The regulations may also reduce the number of suppliers who provide conflict-free metals, and may affect our ability to obtain products in sufficient quantities or at competitive prices. Finally, some of our customers may elect to disqualify us as a supplier if we are unable to verify that the metals used in our products are free of conflict minerals.

Our failure to protect and defend our intellectual property could impair our ability to compete effectively.

We rely on patent, trademark, trade secret, copyright and mask work laws to protect our intellectual property, proprietary information and technology rights. As of December 31, 2013, we owned more than 3,000 U.S. patents and 490 foreign patents, and had more than 1,200 patents applications pending worldwide. Our patents and patent applications may not protect us from our competition, which may be able to circumvent our patents or develop new patentable technologies that displace our products. In addition, other parties, including our former employees or consultants, may try to disclose, obtain or use our proprietary information or technologies without our authorization despite our best efforts at prevention. If other companies obtain this information or develop similar information or technologies, they may develop products that compete against ours.

Moreover, the laws of certain countries where we sell, manufacture or distribute products may not protect our products and intellectual property rights to the same extent as U.S. laws. Policing the unauthorized use of our products is difficult and costly and could divert the efforts of our technical and management personnel. Even if we spend significant resources and efforts to protect our intellectual property, we may be unable to prevent misappropriation of our technology. If others use our proprietary rights, it could materially harm our business and require expensive litigation to enforce our intellectual property rights.

Intellectual property infringement claims could adversely affect our ability to manufacture and market our products.

We occasionally receive inquiries about possible patent infringements that may require us to obtain licenses relating to our current or future products. We may be unable to obtain licenses on reasonable terms, or the license agreements may have set durations or may not provide complete protection against infringement claims involving all of our current or future products. If we are sued for patent infringement, the costs and outcome of litigation will be unpredictable and may have a negative impact on our financial results. Intellectual property claims, regardless of their merit, can result in costly litigation and divert the efforts of our technical and management personnel. Legal proceedings are also unpredictable and may be affected by events outside of our control. If our

defense against intellectual property infringement claims is unsuccessful, we may be required to pay significant monetary damages or be subject to an injunction against the manufacture and sale of one or more of our product families. Alternatively, we could be required to spend significant resources to develop non-infringing technology, the success of which may be uncertain. Intellectual property litigation may have an adverse effect on our financial position, results of operations and cash flows.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

None.

ITEM 2. PROPERTIES.

Our headquarters facility currently consists of four interconnected buildings totaling approximately 505,000 square feet, located on approximately 24 acres of land that we own in San Jose, California. Design, research, marketing, administrative, and limited manufacturing activities are performed in this facility. We also have a 470,000-square-foot design, test engineering, operation and administrative facility in Penang, Malaysia, located on land leased on a long-term basis. We lease our domestic and international offices, including our technology centers in the United Kingdom, Canada, Denmark and the United States. We believe that our facilities are adequate for our current and foreseeable future needs.

ITEM 3. LEGAL PROCEEDINGS.

On December 8, 2010, Intellectual Ventures I LLC and Intellectual Ventures II LLC (“Intellectual Ventures”) filed a lawsuit in the United States District Court for the District of Delaware against Altera, Microsemi Corporation, and Lattice Semiconductor Corporation alleging that Altera infringes five patents. The complaint requests unspecified monetary damages including enhanced damages for willful infringement. In February 2011, Intellectual Ventures filed a First Amended Complaint adding Xilinx, Inc. as a defendant. In March 2011, Altera answered the complaint and asserted counterclaims against Intellectual Ventures for non-infringement and invalidity of the asserted patents. The defendants filed motions in the District of Delaware to transfer the case to the United States District Court for the Northern District of California and to stay the action pending re-examination proceedings in the United States Patent and Trademark Office. Intellectual Ventures opposed the motions. In January 2012, the United States District Court for the District of Delaware denied the defendants' motion to transfer the case to the Northern District of California, and in February 2012, the court denied the defendants' motion to stay. Three of the four defendants, including Altera, filed a writ of mandamus in the Court of Appeals for the Federal Circuit requesting that the case be transferred to the Northern District of California. In July 2012, the Court of Appeals for the Federal Circuit denied the writ of mandamus. In January 2013, Intellectual Ventures and Microsemi announced a settlement agreement, which included a dismissal of all claims against Microsemi. In March 2013, Intellectual Ventures and Lattice announced a settlement agreement, which included a dismissal of all claims against Lattice. In December 2013, Intellectual Ventures and Altera entered into a settlement agreement, which included a dismissal of all Intellectual Ventures’ claims against Altera and a dismissal of all Altera’s counterclaims against Intellectual Ventures. The resolution of this case did not have a material adverse impact on our consolidated results of operations.

We file income tax returns with the Internal Revenue Service (“IRS”) and in various U.S. states and foreign jurisdictions. On December 8, 2011 and January 23, 2012, the IRS issued Statutory Notices of Deficiency (the “Notices”) determining, respectively, additional taxes for 2002 through 2004 of $19.8 million and additional taxes for 2005 through 2007 of $21.4 million, excluding interest. The IRS’s determinations relate primarily to inter-company transactions, computational adjustments to the research and development ("R&D") credit and reductions to the benefits of tax credit carry backs and carry forwards. We deposited $18.0 million as a cash bond with the IRS in 2008, and converted this amount to tax payments in March 2012. On March 6, 2012 and April 20, 2012, we filed petitions challenging the two Notices respectively, in the U.S. Tax Court. The petitions request redetermination of the deficiencies produced by the IRS’s adjustments. The IRS has filed responses to our petitions, in which the IRS conceded the R&D credit adjustment for 2004. The Tax Court has consolidated the two cases and a judge has been assigned. The federal statute of limitations for the 2002 and 2003 tax years has expired, and the ongoing Tax Court litigation concerns only the 2004 through 2007 years.

On January 31, 2013, the IRS conceded one of the adjustments at issue in the litigation for the 2004 through 2007 tax years. The conceded adjustment related to certain inter-company services transactions. The concession only impacted our 2007 tax year. As a result of this concession, we recognized a tax and interest benefit of $6.8 million during the three months ended March 29, 2013 due to the release of certain tax reserves. Altera and the IRS have filed cross motions for partial summary judgment on the largest adjustment still at issue, which is related to the treatment of stock-based compensation in an inter-company cost-sharing transaction. As part of the partial motion for summary judgment process, both sides filed briefs on May 28, 2013, July 25, 2013 and September 9, 2013. We expect to present additional legal arguments related to certain affirmative adjustments raised by Altera in the litigation. The parties filed a Joint Status Report addressing these affirmative adjustments with the Tax Court on February 5, 2014. We believe we have made adequate tax payments or accrued adequate amounts for our tax liabilities for 2004 through 2007 and that the outcome of the above matters will not have a material adverse effect on our consolidated operating results or financial position.

On April 19, 2013, the IRS notified us that we would be audited for each of the 2010 and 2011 tax years. We believe we have made adequate tax payments or accrued adequate amounts for our tax liabilities for 2010 and 2011 and that the outcome of the audit will not have a material adverse effect on our consolidated operating results or financial position.

Our net sales for 2013 were down 3% from 2012 as we were impacted by reduced demand in certain vertical markets, particularly in Telecom & Wireless, driven by the lack of demand in the Telecom sub-vertical. Of our eleven sub-vertical markets, seven grew during 2013 as we had continued success in penetrating new markets and displacing ASICs in existing markets. Our Industrial Automation, Military and Automotive sub-vertical markets each grew in 2013. Our Networking, Computer & Storage sub-vertical markets also increased as we are in the early stage of FPGA adoption in data center applications. The Telecom & Wireless sub-vertical markets each decreased, with Telecom down significantly, as carriers redirected spending to Wireless. Wireless was down slightly due to an ASIC conversion partially offset by an increase in Long-Term Evolution (LTE) related growth in China that positively impacted our second-half revenue. Our gross margin percentage for 2013 decreased from 69.6% to 68.4%, due to an unfavorable mix in vertical markets along with an unfavorable customer and product mix within the sub-vertical markets.

Our fourth quarter net sales of $454.4 million increased 2% sequentially from the third quarter of 2013 as a result of improved demand in certain vertical markets, particularly in Networking, Computer & Storage, with the Computer sub-vertical market up sharply. The Telecom & Wireless sub-vertical markets were flat. Industrial Automation, Military and Automotive decreased slightly, although the Industrial sub-vertical market had growth for the third consecutive quarter. Our gross margin percentage increased slightly to 68.4% when compared to the third quarter gross margin percentage of 68.3%.

Our 28-nanometer and 40-nanometer product families continue to be the most significant contributors to revenue, driving the 10% sequential and 31% annual growth in our New Product category.

During 2013, we made significant strategy and product announcements. During the first quarter, we announced that we had entered into an agreement with Intel for the future manufacture of certain Altera FPGAs on Intel's 14 nm Tri-Gate transistor technology. This established us as the only major FPGA company with access to this technology, which we believe will significantly strengthen our next-generation competitive position. During the second quarter, we announced our Generation 10 FPGAs and SoC FPGAs, which will offer system developers higher levels of performance and power efficiency. During the fourth quarter, we released a new version of our Quartus II Software that supports our Arria 10 FPGAs, making us the first FPGA supplier to offer publicly available software support for 20 nm FPGAs.

We continue to generate strong operating cash flows, with $590.2 million in cash flows from operations for 2013. We returned $361.5 million, or 61.3%, of the cash flow from operations to our stockholders during the year in the form of dividends and repurchases of common stock. During the fourth quarter of 2013, for the second time in two years, we capitalized on the continued low interest rate environment, issuing $1 billion in senior notes for general corporate purposes including future common stock repurchases. We ended the year with $4.7 billion in cash, cash equivalents and investments. On January 20, 2014, our board of directors declared a cash dividend of $.0.15 per share for the first quarter of 2014.

We continue to evaluate strategic business acquisitions and, during 2013, we made two key acquisitions to enhance our product offerings. During the first quarter, we acquired TPACK. TPACK's FPGA-based optical transport network (OTN) IP and expertise will enable us to accelerate and expand our OTN solutions road map. During the second quarter, we acquired Enpirion, Inc., a leading provider of high-efficiency, integrated power conversion products known as PowerSoCs. We believe the combination of our FPGAs with Enpirion's PowerSoCs offers customers higher performance, lower system power, higher reliability, smaller footprint and faster time-to-market.

We believe that we are well positioned in many of our vertical markets to see growth that will primarily be driven by our New Product category.

Critical Accounting Estimates

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires our management to make certain judgments and estimates that affect the amounts reported in our consolidated financial statements. Our management believes that we consistently apply these judgments and estimates and the consolidated financial statements fairly represent all periods presented. However, any differences between these judgments and estimates and actual results could have a material impact on our consolidated statements of comprehensive income and our consolidated balance sheets. Critical accounting estimates, as defined by the Securities and Exchange Commission (“SEC”), are those that are most important to the portrayal of our financial condition and results of operations and require our management's most difficult and subjective judgments and estimates of matters that are inherently uncertain. Our critical accounting estimates include those regarding (1) revenue recognition; (2) valuation of inventories; and (3) income taxes.

Revenue Recognition

We sell the majority of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In most cases, sales to distributors are made under agreements allowing for subsequent price adjustments and returns. We generally defer recognition of revenue and costs until the products are resold by the distributor. Our revenue reporting is highly dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us with periodic data regarding the product, price, quantity and end customer when products are resold as well as the quantities of our products they still have in stock. We maintain system controls to validate distributor data and to verify that reported data is accurate. At times, we must use estimates and apply judgments to reconcile distributors' reported inventories to their activities. This reconciliation process requires us to estimate the amount of in-transit shipments (net of in-transit returns) to our distributors. In-transit days can significantly vary among geographies and individual distributors. We also apply judgment when estimating the total value of price concessions earned by our distributors but not claimed by the end of the reporting period. This is because there is a time lag between the price concessions earned and claimed by the distributors for any underlying resale of products. Any error in our judgment could lead to inaccurate reporting of our net sales, deferred income and allowances on sales to distributors, and net income.

Valuation of Inventories

Inventories are recorded at the lower of cost determined on a first-in-first-out basis (approximated by standard cost) or market. We routinely compare our inventory against projected demand and record provisions for excess and obsolete inventories as necessary. We establish provisions for inventory for technological obsolescence or if inventory levels on hand are in excess of projected customer demand. Such provisions result in a write-down of inventory to net realizable value and a charge to cost of sales. Historically, it has been difficult to forecast customer demand. Actual demand may materially differ from our projected

demand, and this difference could have a material impact on our gross margin and inventory balances based on additional provisions for excess or obsolete inventory or a benefit from inventory previously written down. Many of the orders we receive from our customers and distributors request delivery of product on relatively short notice and with lead times less than our manufacturing cycle time. In order to provide competitive delivery times to our customers, we build and stock a certain amount of inventory in anticipation of customer demand that may not materialize. Moreover, as is common in the semiconductor industry, we generally allow customers to cancel orders with minimal advance notice. Thus, even product built to satisfy specific customer orders may not ultimately be required to fulfill customer demand.

Income Taxes

We establish a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and for operating losses and tax carryforwards. We record valuation allowances, when necessary, to reduce our deferred tax assets to the amount that management estimates is more likely than not to be realized. If, in the future, we determine that we are not likely to realize all or part of our net deferred tax assets, an adjustment to the deferred tax asset valuation allowance would be recorded as a charge to earnings in the period such determination is made.

We measure and recognize uncertain tax positions in accordance with U.S. GAAP, whereby we only recognize the tax benefit from an uncertain tax position if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the merits of the position.

The calculation of our tax liabilities involves the inherent uncertainty associated with the application of U.S. GAAP and complex tax laws. We are subject to examination by various taxing authorities. We believe we have adequately provided in our financial statements for additional taxes that we estimate may be required to be paid as a result of such examinations. If the payment ultimately proves to be unnecessary, the reversal of the tax liabilities would result in tax benefits being recognized in the period we determine the liabilities are no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, an additional charge to expense will result.

Results of Operations

Results of operations expressed as a percentage of net sales were as follows:



	2013		2012		2011
Net sales	100.0	%	100.0	%	100.0	%
Cost of sales	31.6	%	30.4	%	29.6	%
Gross margin	68.4	%	69.6	%	70.4	%

Net income	25.4	%	31.2	%	37.3	%

Net sales were $1.73 billion in 2013, $1.78 billion in 2012 and $2.06 billion in 2011. Net sales decreased by 3% in 2013 from 2012. The decrease in Net sales in 2013 was mainly due to a typical decline in Mature and Other Products coupled with a moderate decline in Mainstream Products as our new technologies are being adopted. Sales of New Products had strong growth in 2013 as we continued to experience growth in our 28-nm and 40-nm products. Net sales declined in the Telecom & Wireless vertical market, partially offset by slight increases in the Industrial, Automation, Military & Automotive and Networking, Computer & Storage vertical markets. We experienced a decrease in net sales in 2013 in Asia Pacific, offset by modest growth in Japan and EMEA.

Net sales decreased by 14% in 2012 from 2011. The Net sales decrease in 2012 was due to a decrease in customer demand across all vertical markets and in all geographies. We saw strong growth in sales of our New Products while there was a decrease in our Mainstream and Mature Product categories.

Huawei Technologies Co., Ltd. (“Huawei”), an original equipment manufacturer ("OEM"), individually accounted for 11% of net sales in 2013, 16% in 2012 and 13% in 2011. No other individual OEM accounted for more than 10% of net sales in 2013, 2012 or 2011. See Note 7: Accounts Receivable, Net and Significant Customers to our consolidated financial statements.

Product Categories

We classify our products into three categories: New, Mainstream, and Mature and Other Products. The composition of each product category is as follows:


•	New Products include the Stratix^® V, Stratix IV, Arria^® V, Arria II, Cyclone^®V, Cyclone IV, MAX^® V, HardCopy^® IV devices and Enpirion PowerSoCs.


•	Mainstream Products include the Stratix III, Cyclone III, MAX II and HardCopy III devices.


•	Mature and Other Products include the Stratix II, Stratix, Arria GX, Cyclone II, Cyclone, Classic™, MAX 3000A, MAX 7000, MAX 7000A, MAX 7000B, MAX 7000S, MAX 9000, HardCopy II, HardCopy, FLEX^® series, APEX™ series, Mercury™, Excalibur™ devices, configuration and other devices, intellectual property cores, and software and other tools.

The product categories above approximate the relative life cycle stages of our products. New Products are primarily comprised of our most advanced products. Customers typically select these products for their latest generation of electronic systems. Demand is generally driven by prototyping and production needs. Mainstream Products are somewhat older products that are generally no longer design-win vehicles. Demand is driven by customers' later stage production-based needs. Mature Products are yet older products with demand generated by the oldest customer systems still in production. This category also includes sales of software, intellectual property and other miscellaneous devices.

Net Sales by product category were as follows:



							Annual Growth Rate
	2013		2012		2011		2013		2012

New	43	%	32	%	22	%	31	%	22	%
Mainstream	27	%	30	%	34	%	(14	)%	(22	)%
Mature and Other	30	%	38	%	44	%	(22	)%	(26	)%
Net Sales	100	%	100	%	100	%	(3	)%	(14	)%

Vertical Markets

The following vertical market data is derived from data that is provided to us by our distributors and end customers. With a broad base of customers, who in some cases manufacture end products spanning multiple market segments, the assignment of net sales to a vertical market requires the use of estimates, judgment and extrapolation. As such, actual results may differ from those reported.

Net Sales by vertical market were as follows:



							Annual Growth Rate
	2013		2012		2011		2013		2012

Telecom & Wireless	41	%	44	%	43	%	(9	)%	(12	)%
Industrial Automation, Military & Automotive	22	%	21	%	23	%	4	%	(22	)%
Networking, Computer & Storage	19	%	17	%	17	%	6	%	(11	)%
Other	18	%	18	%	17	%	(3	)%	(10	)%
Net Sales	100	%	100	%	100	%	(3	)%	(14	)%

FPGAs and CPLDs

Our PLDs consist of field-programmable gate arrays, or FPGAs, including those referred to as system-on-chip FPGAs ("SoC FPGAs") that incorporate hard embedded processor cores, and complex programmable logic devices, or CPLDs. FPGAs consist of our Stratix, Cyclone, Arria, APEX, FLEX and ACEX 1K, as well as our Excalibur and Mercury families. CPLDs consist of our MAX and Classic families. Other Products consist of our Enpirion PowerSoCs, HardCopy ASIC devices, configuration devices, software and other tools and IP cores.

Net sales of FPGAs, CPLDs and Other Products were as follows:



							Annual Growth Rate
	2013		2012		2011		2013		2012

FPGA	83	%	84	%	81	%	(4	)%	(11	)%
CPLD	9	%	9	%	10	%	(4	)%	(22	)%
Other Products	8	%	7	%	9	%	9	%	(27	)%
Net Sales	100	%	100	%	100	%	(3	)%	(14	)%

Price Concessions and Product Returns from Distributors

We sell the majority of our products to distributors worldwide at a list price. Our distributors resell our products to end customers at a very broad range of individually negotiated prices based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. To receive price concessions, distributors must submit the price concession claims to us for approval within 60 days of the resale of the product to an end customer. Primarily because of the uncertainty related to the final price, we defer revenue recognition on sales to distributors until

our products are sold from the distributor to the end customer, which is when our price is fixed or determinable. Accordingly, these pricing uncertainties impact our results of operations, liquidity and capital resources. Total price concessions earned by distributors were $4.6 billion and $4.3 billion for 2013 and 2012, respectively. See Note 10: Deferred Income and Allowances on Sales to Distributors to our consolidated financial statements. Average aggregate price concessions typically range from 70% to 85% of our list price on an annual basis, depending upon the composition of our sales, volume and factors associated with timing of shipments to distributors or payment of price concessions.

Our distributors have certain rights under our contracts to return defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return unsold product to Altera, subject to certain contract limits, based on a percentage of sales occurring over various periods prior to the stock rotation. Products resold by the distributor to end customers are no longer eligible for return, unless specifically authorized by us. In addition, we generally warrant our products against defects in material, workmanship and non-conformance to our specifications. Returns from distributors totaled $88.1 million and $82.6 million for 2013 and 2012, respectively. See Note 10: Deferred Income and Allowances on Sales to Distributors to our consolidated financial statements.

Gross Margin



	2013		2012		2011

Gross Margin Percentage	68.4	%	69.6	%	70.4	%

Our gross margin rates are heavily influenced by both vertical market mix and the timing of material cost improvements. While these variables will continue to fluctuate on a cyclical basis, our gross margin target over the long term is 67%. We believe that the 67% gross margin target will enable us to achieve our desired balance between growth and profitability. Our gross margin percentage decreased in 2013 by 1.2 points when compared with 2012. The decrease was primarily attributable to an unfavorable mix within vertical markets along with an unfavorable customer and product mix within certain of the vertical markets when compared with 2012.

Our gross margin percentage decreased in 2012 by 0.8 points when compared with 2011. The decrease was primarily attributable to an unfavorable vertical market mix when compared with 2011.

Research and Development Expense

Research and development expense includes costs for compensation and benefits, development masks, prototype wafers, and depreciation and amortization. These expenditures are for the design of new products, the development of process technologies, new package technology, software to support new products and design environments, and IP cores.

We will continue to make significant investments in the development of new products and focus our efforts on the development of new programmable logic devices that use advanced semiconductor wafer fabrication processes, as well as related development software. We are currently investing in the development of future silicon products, as well as our Quartus II software, PowerSoCs, library of IP cores and other future products.



($ in millions)	2013			2012			2011			2013 vs. 2012 Change		2012 vs. 2011 Change

Research and Development Expense	$	385.2		$	359.6		$	324.2		7	%	11	%

Percentage of Net Sales	22.2		%	20.2		%	15.7		%

Research and development expense for 2013 increased by $25.6 million, or 7%, compared with 2012. The increase was primarily attributable to a $24.4 million increase in personnel-related costs due to an increase in the number of employees to support product development and from our recent acquisitions, a $6.9 million increase in depreciation expense, a $6.2 million increase in variable compensation expense, a $2.7 million increase in rental and license costs in connection with our product development activities, a $2.6 million increase in professional services, and a $0.9 million increase in stock-based compensation expense due to an increase in the number of employees. These increases were partially offset by an $18.8 million decrease related to timing of external costs for product development activities.

Research and development expense for 2012 increased by $35.4 million, or 11%, compared with 2011. The increase was primarily attributable to a $27.4 million increase in personnel-related costs due to an increase in the number of employees, a $12.4 million increase in product development activities, a $6.8 million increase in rental and telephone expense, a $5.2 million increase in stock-based compensation driven by an increase in the number of employees and a $4.8 million increase in depreciation and maintenance and repair expenses. These increases were partially offset by a $24.4 million decrease in variable compensation expenses based on lower operating results in 2012.

Selling, General, and Administrative Expense

Selling, general, and administrative expense primarily includes compensation and benefits related to sales, marketing and administrative employees, commissions and incentives, depreciation, legal, advertising, facilities and travel expenses.



($ in millions)	2013			2012			2011			2013 vs. 2012 Change		2012 vs. 2011 Change

Selling, General and Administrative Expense	$	320.1		$	289.9		$	279.2		10	%	4	%

Percentage of Net Sales	18.5		%	16.3		%	13.5		%

Selling, general, and administrative expense for 2013 increased by $30.2 million, or 10%, when compared with 2012. The increase was primarily attributable to a $12.8 million increase in personnel-related costs due to an increase in the number of employees to support the business, a $4.5 million increase in variable compensation expense, a $3.8 million increase in professional services and consulting fees, a non-recurring $3.0 million increase in local, non-income taxes, a $2.5 million increase in depreciation expense, a $2.1 million increase in stock-based compensation due to an increase in the number of employees, and a $2.1 million increase in rental and license costs.

Selling, general, and administrative expense for 2012 increased by $10.7 million, or 4%, when compared with 2011. The increase was primarily attributable to a $9.8 million increase in personnel-related costs due to an increase in the number of employees to support the business, a $5.4 million increase in stock-based compensation driven by an increase in the number of employees, and an $8.4 million increase in professional services and consulting fees. These increases were partially offset by a $13.4 million decrease in variable compensation expenses based on lower operating results in 2012.

Amortization of Acquisition-Related Intangible Assets

Amortization of acquisition-related intangible assets for 2013 increased by $4.0 million when compared with 2012, primarily due to the acquisitions in the second quarter of 2013.

Deferred Compensation Plan

We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (the “NQDC Plan”). Since the inception of the NQDC Plan, we have not made any contributions to the NQDC Plan and we have no commitments to do so in the future. There are no NQDC Plan provisions that provide for any guarantees or minimum return on investments. Investment income or loss earned by the NQDC Plan is recorded as (Gain) loss on deferred compensation plan securities in our consolidated statements of comprehensive income. We reported (gain)/ loss on NQDC Plan assets of $(10.6) million, $(7.1) million and $2.0 million in 2013, 2012 and 2011, respectively. These amounts resulted from the overall market performance of the underlying securities. The investment (gain)/loss also represents an (increase) decrease in the future payout to employees and is recorded as Compensation expense (benefit) - deferred compensation plan in our consolidated statements of comprehensive income. The compensation expense (benefit) associated with our deferred compensation plan obligations is offset by (gain)/loss from related securities. The net effect of the investment income or loss and related compensation expense or benefit has no impact on our income before income taxes, net income, or cash balances. See Note 18: Employee Benefits Plans to our consolidated financial statements for a detailed discussion of our NQDC Plan.

Interest Income and Other

Interest income and other consists mainly of interest income generated from investments in bonds, money market funds and high-quality fixed income securities. The increase in Interest income and other in both 2013 and 2012 compared with 2012 and 2011,

respectively, was primarily due to higher cash and investments and changes in our investment portfolio composition during 2013 and 2012 that generated higher investment income.

Interest Expense

The increase in Interest expense in 2013 compared with 2012 was mainly attributable to the new long-term debt issued in the fourth quarter of 2013 and a one-time interest charge on debt assumed in connection with our acquisitions in the second quarter of 2013. See Note 19: Credit Facility and Long-Term Debt for further discussion.

The increase in Interest expense in 2012 compared with 2011 was mainly due to the long-term debt issued in the second quarter of 2012, which has a higher effective interest rate than the former credit facility.

Income Tax Expense

Our effective tax rate reflects the impact of significant amounts of our earnings being taxed in foreign jurisdictions at rates substantially below the U.S. statutory rate. Our effective tax rates were 6.5% for 2013, 5.9% for 2012 and 9.2% for 2011.

The net increase in our effective tax rate in 2013 when compared with 2012 was primarily due to lower one-time tax benefits in 2013 compared to 2012, partially offset by the absence of a U.S. federal research and development tax credit in 2012, which expired in 2011. During 2013, the effective tax rate included the benefit of $10.6 million resulting from the enactment of the American Taxpayer Relief Act in January 2013, which retroactively extended the federal research and development credit for two years from January 1, 2012 through December 31, 2013. In addition, we reversed $6.8 million of liabilities for uncertain tax liabilities after the IRS conceded an adjustment for certain 2007 inter-company transactions in our litigation regarding the 2004 through 2007 tax years (plus related interest), $2.3 million of liabilities for uncertain tax positions relating to changes in estimates for certain foreign tax jurisdictions, and $30.3 million of liabilities for uncertain tax positions upon the expiration of foreign and domestic statutes of limitation and related interest, which was substantially offset by $27.7 million of tax accrued on foreign dividends. For 2012, the effective tax rate included tax benefits associated with the following: a release of liabilities for uncertain tax positions of $24.4 million, primarily associated with the expiration of the federal statutes of limitation, the reassessment and recognition of previously unrecognized federal tax benefits and the reversal of the related interest accruals, a $6.9 million net tax benefit as a result of a Statutory Notice of Deficiency received from the IRS for 2005 to 2007, and a $9.1 million net tax benefit as a result of the expiration of the statutes of limitations for certain foreign jurisdictions.

During the fourth quarter of fiscal 2013 we recorded a deferred charge for the deferral of income tax expense on intercompany profits that resulted from the sale of our newly acquired intellectual property rights from an Altera U.S. entity to one of our foreign subsidiaries. The deferred charge is included in Other current assets and Other assets, net on our consolidated balance sheets. As of December 31, 2013, the deferred charge balance in Other current assets was $2.2 million, and $18.9 million in Other assets, net. The deferred charge will be amortized on a straight-line basis as a component of income tax expense over ten years, based on the economic life of the intellectual property and is not expected to have a material impact on our effective tax rate.

The significant net decrease in our effective tax rate in 2012 when compared with 2011 was primarily due to higher one-time tax benefits in 2012 compared to 2011, partially offset by the absence of a U.S. federal research and development tax credit in 2012, due to its expiration in 2011. For 2012, the effective tax rate includes the following net tax benefits associated with the release of liabilities for uncertain tax positions: a $24.4 million net tax benefit primarily associated with the expiration of the federal statutes of limitation, the reassessment and recognition of previously unrecognized federal tax benefits, and the reversal of the related interest accruals; a $6.9 million net tax benefit as a result of a Statutory Notice of Deficiency received from the IRS for 2005 to 2007; and a $9.1 million net tax benefit as a result of the expiration of the statutes of limitations for certain foreign jurisdictions. In 2011, we reversed $4.3 million of liabilities for uncertain tax positions as a result of a Statutory Notice of Deficiency received from the Internal Revenue Service for 2002 through 2004. In addition, in 2011 we reversed $8.2 million of liabilities for uncertain tax positions upon expiration of the statutes of limitations and settlement with certain foreign jurisdictions.

Financial Condition, Liquidity, Credit Facility and Capital Resources

Overview

We derive our liquidity and capital resources primarily from our cash flows from operations. We continue to generate strong positive operating cash flows. In October 2013, we issued $600 million aggregate principal amount of 2.5% senior notes (the "2.50% Notes") and $400 million aggregate principal amount of 4.10% senior notes (the "4.10% Notes") that will mature on November 15, 2018, and November 15, 2023, respectively, for general corporate purposes, including stock repurchases (collectively the "2013 Notes"). In May 2012, we issued $500 million aggregate principal amount of 1.75% senior notes (the "1.75% Notes")

that will mature on May 15, 2017 to repay our former credit facility (the "2012 Notes"). In June 2012, we entered into a credit agreement that provides for a $250 million unsecured revolving line of credit (the "Facility"), which is scheduled to mature in June 2017. As of December 31, 2013, we had no borrowings under the Facility. As such, the $250 million available under the Facility represents a source of liquidity. See Note 19: Credit Facility and Long-Term Debt to our consolidated financial statements for further discussion.

We purchased $1.5 billion in U.S. Treasury securities over the past two years, which provide an approximate economic hedge of the interest rate exposure on our 2013 and 2012 Notes. Overall, our investment portfolio is invested primarily in highly-rated securities and our investment policy generally limits the amount of credit exposure to any one issuer. The policy requires investments generally to be investment grade with the objective of minimizing the potential risk of principal loss.

We currently use cash to fund dividends, capital expenditures and repurchases of our common stock. Based on past performance and current expectations, we believe that our existing cash, cash equivalents, investments, together with cash expected to be generated from operations, the Facility and our access to capital markets will be sufficient to satisfy our operations, cash dividends, capital expenditures and stock repurchases over the next 12 months.

Common Stock Repurchases and Dividends

We repurchase shares under our stock purchase program announced on July 15, 1996, which has no specified expiration. No existing repurchase plans or programs have expired, nor have we decided to terminate any repurchase plans or programs prior to expiration. On August 28, 2013, we announced that our board of directors increased the share repurchase program authorization by an additional 30.0 million shares. Combined with the board’s previous authorization in prior years, there is a total of 233.0 million shares authorized for repurchase with approximately 36.8 million shares remaining for further repurchases under our stock repurchase program as of December 31, 2013. Since the inception of the stock purchase program through December 31, 2013, we have repurchased a total of 196.2 million shares of our common stock for an aggregate cost of $4.3 billion. Management believes that this authorization is sufficient to support the company's share repurchase objectives through mid-2015.

Common stock repurchase activity was as follows:



(In millions, except per share amounts)	2013		2012		2011

Shares repurchased	6.2		6.9		4.8

Average price per share	$	32.33	$	33.10	$	41.05

In 2013, we paid $160.4 million in cash dividends to stockholders, representing $0.15 per common share for an aggregate amount of $96.4 million in the third and fourth quarters of 2013 and $0.10 per common share for an aggregate amount of $64.0 million in the first and second quarters of 2013. On January 20, 2014, our board of directors declared a cash dividend of $0.15 per share for the first quarter of 2014.

Shelf Registration Statement

We have an effective shelf registration statement on file with the Securities and Exchange Commission that allows us to issue senior debt securities from time to time in one or more offerings. Each issuance under the shelf registration will require the filing of a prospectus supplement identifying the amount and terms of the securities to be issued. The registration statement does not limit the amount of debt securities that may be issued thereunder. Our ability to issue debt securities is subject to market conditions and other factors impacting our borrowing capacity, including our credit ratings and compliance with the covenants in our credit agreement.

Cash Flows

Our cash and cash equivalents balance decreased by $7.5 million during the year ended December 31, 2013. The change in cash and cash equivalents for 2013, 2012 and 2011 was as follows:



(In millions)	2013			2012			2011
Net cash provided by operating activities	$	590.2		$	587.2		$	959.6
Net cash used in investing activities	(1,236.5		)	(767.2		)	(170.9		)
Net cash provided by (used in) financing activities	638.8			(315.3		)	(181.9		)
Net (decrease) increase in cash and cash equivalents	$	(7.5	)	$	(495.3	)	$	606.8

Total cash and cash equivalents accounted for 48% and 62% of total assets at December 31, 2013 and 2012, respectively.

Operating Activities

In 2013, our operating activities provided $590.2 million in cash, primarily attributable to net income of $440.1 million, adjusted for non-cash stock-based compensation expense of $98.9 million (net of related tax effects), depreciation and amortization (including amortization of acquisition-related intangible assets) of $52.0 million, a deferred income tax expense of $3.6 million, net amortization of investment discount/premium of $3.4 million, and amortization of debt discount and debt issuance costs of $1.5 million. The net change in working capital accounts (excluding cash and cash equivalents and effects of acquisitions) was primarily due to a $157.8 million increase in Accounts receivable, net, a $7.9 million increase in Inventories, a $1.3 million increase in Other assets, a $9.4 million increase in Accounts payable and other liabilities, a $139.0 million increase in Deferred income and allowances on sales to distributors, and a $14.4 million increase in Income tax payable.

Our sales to distributors are primarily made under agreements allowing for subsequent price adjustments and returns in most cases, and we generally defer recognition of revenue until the products are resold by the distributor. At the time of shipment to distributors for the majority of our sales, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (2) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to distributors in the liability section of our consolidated balance sheets. Increases in Accounts receivable, net associated with higher billings are generally offset by corresponding increases in Deferred income and allowances on sales to distributors. However, timing differences between gross billings, discounts earned, collections, revenue recognition and changes in the mix of sales to OEMs and distributors may result in a temporary interruption to the normal relationship between these two accounts.

The $157.8 million increase in Accounts receivable, net, and the $139.0 million increase in Deferred income and allowances on sales to distributors was primarily attributable to increased gross billings to distributors near the end of the period in the fourth quarter of 2013 compared with the same period in 2012. A contributing factor to the increase in Accounts receivable, net was due to timing of utilization of subsequent price concessions by certain distributors.

The $7.9 million increase in Inventories was attributable to an increase in purchases to support new products in the fourth quarter of 2013 compared with the same period in 2012.

The $1.3 million increase in Other assets is primarily attributable to a deferred charge related to the deferral of income tax expense on intercompany profits that arose from the sale of our newly acquired intellectual property rights from an Altera U.S. entity to one of our foreign subsidiaries, an increase in income taxes receivable due to prior year overpayments of domestic income taxes and an increase in interest receivable due to the increase in the balance of our investment portfolio. These increases were offset by a decrease due to the timing of other prepaid items.

The $9.4 million increase in Accounts payable and other liabilities was primarily attributable to an increase in accrued interest payable due to our bond offering in the fourth quarter of 2013, an increase in accrued variable compensation and also for certain compensation arrangements as a result of our recent acquisitions and an increase in accounts payable and various other accrued liabilities due to timing.

The $14.4 million increase in Income taxes payable was primarily related to higher tax liabilities in the U.S. and certain foreign jurisdictions along with timing of certain tax payments.

In 2012, our operating activities provided $587.2 million in cash, primarily attributable to net income of $556.8 million, adjusted for non-cash stock-based compensation expense of $87.1 million (net of related tax effects), depreciation and amortization

(including amortization of acquisition-related intangible assets) of $36.9 million, a deferred income tax expense of $8.8 million and changes in working capital accounts. Significant changes in working capital accounts (excluding cash and cash equivalents) included a $91.4 million increase in Accounts receivable, net, a $30.4 million increase in Inventories, a $3.7 million increase in Other assets, a $50.6 million decrease in Accounts payable and other liabilities, a $66.1 million increase in Deferred income and allowances on sales to distributors, and an $8.6 million increase in Income taxes payable.

Investing Activities

During 2013, our investing activities resulted in a use of cash, primarily for the purchase of available for sale securities of $1.3 billion. This included $1.0 billion used to purchase U.S. Treasury securities, which provide an approximate economic hedge of the interest rate exposure on our 2013 Notes. In addition, we paid $145.3 million (net of cash acquired) for acquisitions, the purchase of other cost basis investments of $7.4 million, purchases of intangible assets of $13.5 million, and purchases of property, plant and equipment of $42.6 million. These items were partially offset by proceeds from the sale of available-for-sale securities of $136.8 million, proceeds from maturity of available-for-sale securities of $178.2 million, and sales of deferred compensation plan securities, net of $4.9 million.

During 2012, our investing activities resulted in a use of cash primarily for the purchase of available for sale securities of $921.4 million. This included $501.1 million used to purchase U.S. Treasury securities, which provide an approximate economic hedge of the interest rate exposure of our 2012 Notes. In addition, we made purchases of property and equipment of $60.9 million and purchases of intangible assets and other investments of $7.2 million, partially offset by cash proceeds from the sale of available-for-sale securities of $105.4 million and proceeds from maturity of available-for-sale securities of $115.4 million.

Financing Activities

During 2013, our financing activities included a use of cash for the repurchase of common stock of $201.1 million, dividend payments of $160.4 million, a use of cash for the payment of debt assumed in acquisitions of $22.0 million, minimum statutory withholding for vested restricted stock units of $28.3 million, and long-term debt and credit facility issuance costs of $4.1 million. These purchases were partially offset by cash proceeds from the issuance of long-term debt of $991.8 million, cash proceeds of $58.2 million from the issuance of common stock to employees through our employee stock plans, and the excess tax benefit from employee stock plans of $4.7 million.

During 2012, our financing activities included repayment of our former credit facility in the aggregate principal amount of $500.0 million, a use of cash for the repurchase of common stock of $229.1 million, dividend payments of $115.5 million, and minimum statutory withholding for vested restricted stock units of $31.5 million, partially offset by cash proceeds of $500.0 million from the issuance of long-term debt and cash proceeds of $49.7 million from the issuance of common stock to employees through our employee stock plans.

Our dividend policy could be impacted in the future by, among other items, future changes in our cash flows from operations and our capital spending needs such as those relating to research and development, investments and acquisitions, common stock repurchases and other strategic investments.

Contractual Obligations

The following table summarizes our significant contractual cash obligations as of December 31, 2013, and the effect that such obligations are expected to have on liquidity and cash flows in future periods:



			Payments Due by Period
(In millions)	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years

Total contractual cash obligations	$	1,967.6	$	211.9	$	90.2	$	1,174.0	$	491.5


(1)	We lease facilities under non-cancelable lease agreements expiring at various times through 2019 and beyond. Rental expense under all operating leases was $10.1 million in 2013, $10.6 million in 2012, and $8.1 million in 2011.


(2)	Due to lengthy subcontractor lead times, we must order materials and services from these subcontractors well in advance, and we are obligated to pay for the materials once they are completed. We expect to receive and pay for these materials in 2014.

(3)

Interest is based on our $600 million aggregate principal amount of 2.50% senior notes (the “2.50% Notes”), our $400 million aggregate principal amount of 4.10% senior notes (the “4.10% Notes”), and our $500 million aggregate principal amount of 1.75% senior notes (the "1.75% Notes"). Interest on the 2.50% Notes, the 4.10% Notes, and the 1.75% Notes is payable semiannually in arrears on May 15 and November 15 of each year. All three of our senior notes are governed by a base and supplemental indenture between Altera and U.S. Bank National Association, as trustee.


(4)	We offer to the majority of our U.S and non-U.S. employees participation in the Service Award Program (“SAP”). The SAP provides employees with one to four weeks of additional paid vacation upon their attainment of five, ten, fifteen, twenty, and twenty-five year service anniversaries. See Note 18: Employee Benefits Plans to our consolidated financial statements.


(5)	As of December 31, 2013, we had $2.8 million of non-cancelable license obligations to providers of electronic design automation software and maintenance expiring at various dates through December 2014.

Due to the uncertainty with respect to the timing of future cash flows associated with our unrecognized tax benefits as of December 31, 2013, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authority. Therefore, $290.5 million of unrecognized tax benefits classified as Income tax payable- non-current in the accompanying consolidated balance sheet as of December 31, 2013, have been excluded from the contractual obligations table above. See Note 16: Income Taxes to our consolidated financial statements for a discussion of income taxes.

In addition to the above obligations, we enter into a variety of agreements and financial commitments in the normal course of business. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments pursuant to such agreements have not been material. We believe that any future payments required pursuant to such agreements would not be significant to our consolidated financial condition or operating results.

Impact of Foreign Currency and Inflation

We have international operations and incur expenditures in currencies other than U.S. dollars. For non-U.S. subsidiaries and branches, foreign currency transaction gains and losses and the impact of the remeasurement of local currency assets and liabilities into U.S. dollars in 2013, 2012 and 2011 were not significant. We do not enter into foreign exchange transactions for trading or speculative purposes.

Off-balance Sheet Arrangements

As of December 31, 2013, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Subsequent Events

On January 20, 2014, our board of directors declared a cash dividend of $0.15 per common share payable on March 3, 2014 to stockholders of record on February 10, 2014.

New Accounting Pronouncements

The information contained in Note 2: Significant Accounting Policies to our consolidated financial statements in Part II, Item 8 under the heading "Recent Accounting Pronouncements" is incorporated by reference into this Part II, Item 7.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Interest Rate Risk

Our exposure to interest rate risk relates primarily to our investment portfolio, which consists of fixed income securities with a fair value of approximately $1.87 billion as of December 31, 2013. Our primary aim with our investment portfolio is to invest available cash while preserving principal and meeting liquidity needs. Our investment portfolio includes U.S. and foreign government and agency securities, corporate bonds, commercial paper, bank certificates of deposit and municipal bonds. In accordance with our investment policy, we place investments with high credit quality issuers and limit the amount of credit exposure to any one issuer. These securities are subject to interest rate risk and will decrease in value if market interest rates increase. A hypothetical 100 basis-point (one percentage point) increase or decrease in interest rates compared to rates at December 31, 2013 would have affected the fair value of our investment portfolio by approximately $79.4 million.

Equity Price Risk

We are exposed to equity price risk inherent in the marketable equity securities held in our investment portfolio and our Non-Qualified Deferred Compensation Plan. A hypothetical 10% adverse change in the stock prices of these equity securities would not result in a material impact on our consolidated financial position, operating results or cash flows.

Foreign Currency Risk

We have international operations and incur expenditures in currencies other than U.S. dollars. To date, our exposure to exchange rate volatility, resulting from foreign currency transaction gains and losses and remeasurement of local currency assets and liabilities into U.S. dollars, has been insignificant. If foreign currency rates were to fluctuate by 10% from rates in effect at December 31, 2013, the resulting transaction gains or losses and the effects of remeasurement would not materially affect our consolidated financial position, operating results or cash flows.

ALTERA CORPORATION

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1: The Company

Altera Corporation was founded in 1983 and reincorporated in the State of Delaware in 1997. We design and sell high-performance, high-density programmable logic devices ("PLDs"), HardCopy application-specific integrated circuit ("ASIC") devices, power system-on-chip devices ("PowerSoCs"), pre-defined design building blocks known as intellectual property ("IP") cores, and associated development tools. Our PLDs, which consist of field-programmable gate arrays ("FPGAs") and complex programmable logic devices ("CPLDs") are semiconductor integrated circuits that are manufactured as standard chips that our customers program to perform desired logic functions within their electronic systems. With our HardCopy devices we offer our customers a migration path from a PLD to a low-cost, high-volume, non-programmable implementation of their designs. Our customers can license IP cores from us for implementation of standard functions in their PLD designs. Customers develop, compile, and verify their PLD designs, and then program their designs into our PLDs using our proprietary development software, which operates on personal computers and engineering workstations. Our products serve a wide range of customers within the Telecom and Wireless, Industrial Automation, Military and Automotive, Networking, Computer and Storage and Other vertical markets.

Note 2: Significant Accounting Policies

BASIS OF PRESENTATION | The consolidated financial statements include our accounts as well as those of our wholly-owned subsidiaries after elimination of all significant inter-company balances and transactions.

Certain prior year amounts in the consolidated financial statements and the notes thereto have been reclassified to conform to the current year presentation. These reclassifications did not affect the prior period total assets, total liabilities, stockholders' equity, net income or net cash provided by operating activities.

USE OF ESTIMATES | The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

CASH EQUIVALENTS AND INVESTMENTS | Cash equivalents consist of highly liquid investments with a maturity of three months or less from the date of original purchase. As of December 31, 2013 and 2012, our cash equivalents consisted of money market funds, corporate bond securities, United States ("U.S.") agency securities and U.S. treasury securities.

As of December 31, 2013, our short-term investments consisted of U.S. agency securities, U.S. treasury securities, non-U.S. government securities, corporate bond securities and municipal bonds with original maturities greater than three months and remaining maturities less than one year from the balance sheet date. Long-term investments consist of U.S. agency securities, U.S. treasury securities, non-U.S. government securities, corporate debt securities and municipal bonds with remaining maturities greater than one year.

Management determines the appropriate classification of investments at the time of purchase and re-evaluates the designations as of each balance sheet date. As of December 31, 2013, all investments in our portfolio, other than those associated with our deferred compensation plan, were classified as available-for-sale. Available-for-sale investments are carried at their fair value based on quoted market prices as of the balance sheet date. Realized gains or losses are determined on the specific identification method and are reflected in Interest income and other in our consolidated statements of comprehensive income. Net unrealized gains or losses are recorded directly in stockholders’ equity on an after-tax basis. Those unrealized losses that are deemed to be other than temporary, of which there were none at December 31, 2013 and 2012, are reflected in Interest income and other. Investments classified as long-term represent funds that are deemed to be in excess of our estimated operating requirements and have remaining maturities exceeding twelve months as of the balance sheet date.

DEFERRED COMPENSATION PLAN - MARKETABLE SECURITIES | We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (the “NQDC Plan”). The investments held in the NQDC Plan consist of publicly traded equity securities, mutual funds and fixed income securities. We account for these investments as trading securities with gains or losses reported as (Gain) loss on deferred compensation plan securities in our consolidated statements of comprehensive income.

DEFERRED COMPENSATION PLAN - RESTRICTED CASH EQUIVALENTS | As of December 31, 2013 and 2012, the cash equivalents held in the NQDC Plan consisted of money market funds and were classified as restricted cash equivalents due to legal restrictions associated with the trust held under the Plan.

INVENTORIES | Inventories are recorded at the lower of actual cost (approximated by standard cost) determined on a first-in-first-out basis or market. We establish provisions for inventory if it is in excess of projected customer demand, and the creation of such provisions results in a write-down of inventory to net realizable value and a charge to cost of sales.

PROPERTY AND EQUIPMENT | Property and equipment are carried at cost less accumulated depreciation and amortization. Cost includes purchase cost, applicable taxes, freight, and installation costs incurred in the acquisition of any assets that require a period of time to make it ready for use. In addition, we capitalize the cost of major replacements, improvements, and betterments, while we expense normal repairs and maintenance. Depreciation and amortization are computed using the straight-line method. Estimated useful lives of three to seven years are used for equipment and office furniture, up to forty years for buildings, and fifty years for land rights. Leasehold improvements and assets recorded under capital leases are amortized over the shorter of the remaining lease term or the estimated useful life of the asset. Property and equipment also includes costs related to the development of internal use software.

BUSINESS COMBINATIONS AND INTANGIBLE ASSETS | Amounts paid for acquisitions are allocated to the tangible assets acquired and liabilities assumed based on their estimated fair value at the date of acquisition. We then allocate the purchase price in excess of net tangible assets acquired to identifiable intangible assets. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions provided by management. We allocate any excess purchase price over the fair value of the net tangible and intangible assets acquired to goodwill. Identifiable intangible assets with finite lives are amortized over their useful lives. Acquisition-related costs, including advisory, legal, accounting, valuation and other costs, are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date. We evaluate the remaining useful life of intangible assets on a periodic basis to determine whether events and circumstances warrant a revision to the remaining useful life. If the estimate of an intangible asset’s remaining useful life is changed, we amortize the remaining carrying value of the intangible asset prospectively over the revised remaining useful life.

LONG-LIVED ASSETS INCLUDING GOODWILL AND ACQUISITION-RELATED INTANGIBLE ASSET IMPAIRMENT | We perform reviews of property, plant and equipment, and certain identifiable intangibles, excluding goodwill, to determine if facts and circumstances indicate that the useful life is shorter than what we had originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, we assess the recoverability of the long-lived assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. In the event such cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets or based on appraisals. Impairment losses, if any, are based on the excess of the carrying amount over the fair value of those assets.

We do not amortize goodwill and intangible assets with indefinite useful lives, rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. We perform our goodwill and intangible asset impairment tests annually during the fourth quarter unless a triggering event would require an expedited analysis.

FAIR VALUE OF FINANCIAL INSTRUMENTS | We define fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. This is sometimes referred to as an "exit price". As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability, also taking into consideration the principal or most advantageous market in which market participants would transact and the market based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk and credit risk. We apply the following fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 - Observable inputs such as quoted prices in active markets

Level 2 - Inputs other than the quoted prices in active markets that are observable either directly or indirectly

Level 3 - Unobservable inputs in which there is little or no market data, which require us to develop our own assumptions

This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure certain financial assets and liabilities at fair value, which consist of our cash equivalents and marketable securities.

Our cash equivalents and investment securities are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include money market securities, exchange traded stocks and open-end mutual funds. Such instruments are generally classified within Level 1 of the fair value hierarchy.

The types of instruments valued based on other observable inputs include bank commercial deposits, corporate commercial paper and municipal obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy. Level 2 pricing is provided by third party sources of market information obtained through our investment advisors, and this market information consists of comparable pricing of other securities as the Level 2 securities we hold are not actively traded and have fewer observable transactions. We do not adjust for or apply any additional assumptions or estimates to the pricing information we receive from our advisors.

We had no transfers between Level 1 and Level 2 during the years ended December 31, 2013 or December 31, 2012.

For certain of our financial instruments, including cash equivalents, accounts receivable, accounts payable, and accrued liabilities, the carrying value approximates fair value due to their short maturities.

CONCENTRATIONS OF CREDIT RISK AND KEY SUPPLIERS | Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash, cash equivalents, and accounts receivable.

We place our cash and cash equivalents in a variety of financial instruments and, by policy, limit the amount of credit exposure through diversification and by restricting our investments to highly rated investment-grade securities.

We sell our products to distributors and original equipment manufacturers (“OEMs”) throughout the world. We attempt to mitigate the concentration of credit risk in our trade receivables through a credit evaluation process, collection terms and by having distributor sales to diverse end customers. Net sales are the sum of our own direct sales to OEMs plus our distributors' resale of Altera products. We rely heavily on two distributors and one OEM to generate a significant portion of our sales.

We currently depend upon Taiwan Semiconductor Manufacturing Company (“TSMC”) to manufacture our silicon wafers. We also depend on TSMC to improve process technologies in a timely manner and to enhance our product designs and cost structure. We have no formalized long-term commitment from TSMC. If market demand for silicon wafers suddenly exceeds market supply, our supply of silicon wafers can become limited quickly. A shortage in foundry manufacturing capacity could hinder our ability to meet demand for our products. Moreover, silicon wafers constitute more than half of our product cost. If we are unable to procure wafers at favorable prices, our gross margins will be adversely affected.

Independent subcontractors, located primarily in Asia, assemble and test our semiconductor products. Because we rely on independent subcontractors to perform these services, we cannot directly control our product delivery schedules or quality levels. Our future success also depends on the financial viability of our independent subcontractors. If the capital structures of our independent subcontractors weaken, we may experience product shortages, quality assurance problems, increased manufacturing costs, and/or supply chain disruption.

The economic, market, social, and political situations in countries where certain independent subcontractors are located are unpredictable, can be volatile, and can have a significant impact on our business because we may not be able to obtain product in a timely manner. Market and political conditions, including manufacturing capacity constraints, currency fluctuation, terrorism, political strife, war, labor disruption, and other factors, including natural or man-made disasters, adverse changes in tax laws, tariff, import or export quotas, power and water shortages, or interruption in air transportation in areas where our independent subcontractors are located also could have a severe negative impact on our operating capabilities.

REVENUE RECOGNITION | We sell the majority of our products to electronic components distributors who resell these products to OEMs, or their subcontract manufacturers. We also sell directly to certain OEMs. In most cases, sales to distributors are made under agreements allowing for subsequent price adjustments and returns, and we generally defer recognition of revenue until the products are resold by the distributor, at which time our final net sales price is fixed. At the time of shipment to distributors, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (2) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to distributors in the liability section of our consolidated balance sheets.

Deferred income effectively represents the gross margin on the sale to the distributor; however, the amount of gross margin we recognize in future periods will be less than the originally recorded deferred income as a result of negotiated price concessions. We sell the majority of our products to distributors worldwide at a list price. However, distributors resell our products to end customers at a very broad range of individually negotiated price points based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. The majority of our distributors' resales are priced at a discount from list price. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. To receive price concessions, distributors must submit the price concession claims to Altera for approval within 60 days of the resale of the product to an end customer. Primarily because of the uncertainty related to the final price, we generally defer revenue recognition on sales to distributors until our products are sold by the distributor to the end customer, which is when our price is fixed or determinable. A substantial portion of Deferred income and allowances on sales to distributors balance represents a portion of distributors' original purchase price that will be credited back to the distributor in the future. The wide range and variability of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in Deferred income and allowances on sales to distributors that will be credited back to the distributors. Therefore, we do not reduce deferred income or accounts receivable by anticipated future price concessions; instead, price concessions are typically recorded against Deferred income and allowances on sales to distributors when incurred, which is generally at the time the distributor sells the product to an end customer.

Our distributors have certain rights under our contracts to return defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return unsold product to Altera, subject to certain contract limits based on a percentage of sales occurring over various periods prior to the stock rotation. Products resold by the distributor to end customers are no longer eligible for return. In addition, we generally warrant our products against defects in material, workmanship and material non-conformance to our specifications.

Revenue from products sold directly to OEMs is recognized upon shipment provided that persuasive evidence of an arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant obligations. We present any taxes assessed by a governmental authority that are both imposed on and concurrent with our sales on a net basis within cost of sales. We record reserves for OEM sales returns and allowances as a component of Accounts receivable, net, in the accompanying consolidated balance sheets.

IMPAIRMENT OF DEFERRED COST OF SALES | Our deferred cost of sales represents the products shipped from Altera to our distributors. We evaluate whether our deferred cost of sales has been impaired based on expected net cash flows to be received for the deferred item. In assessing the impairment of our deferred cost of sales, we use a lower of cost or market estimate of realizable value. We apply our inventory valuation procedures, including potential impairment due to excess or obsolescence, to Altera owned inventory and distributor owned inventory. Realization of the deferred cost occurs because we earn revenue in excess of the amount of costs deferred.

DERIVATIVE FINANCIAL INSTRUMENTS | We account for derivative instruments activities as either assets or liabilities in the statement of financial position and carry them at fair value. Derivatives that are not designated as cash flow hedges for accounting purposes are adjusted to fair value through earnings. We do not enter into foreign exchange transactions for trading or speculative purposes. We did not have any open derivative contracts as of December 31, 2013 or 2012.

INDEMNIFICATION AND PRODUCT WARRANTY | We indemnify certain customers, distributors, suppliers, and subcontractors for attorneys' fees and damages and costs awarded against these parties in certain circumstances in which our products are alleged to infringe third party intellectual property rights, including patents, trade secrets, trademarks, or copyrights. We cannot estimate the amount of potential future payments, if any, that we might be required to make as a result of these agreements. To date, we have not paid any claims nor have we been required to defend any action related to our indemnification obligations, and accordingly, we have not accrued any amounts for such indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations.

We generally warrant our devices for one year against defects in materials, workmanship and material non-conformance to our specifications. We accrue for known warranty issues if a loss is probable and can be reasonably estimated, and accrue for estimated but unidentified issues based on historical activity. If there is a material increase in customer claims compared with our historical experience or if the costs of servicing warranty claims are greater than expected, we may record a charge against cost of sales. Warranty expense was not significant for any period presented in our consolidated statements of comprehensive income.

INCOME TAXES | Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been reflected in the financial statements. Deferred tax assets and liabilities are determined based on the differences between

the book and tax bases of assets and liabilities and operating loss carryforwards, using tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided to reduce net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. The tax benefit of any tax position that meets the more-likely-than-not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the uncertainty. To the extent a full benefit is not expected to be realized on the uncertain tax position, an income tax liability is established. Interest and penalties on income tax obligations, including uncertain tax positions, are included in income tax expense.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from current estimates of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities may result in income tax benefits being recognized in the period when it is determined that the liabilities are no longer necessary. A significant portion of these potential tax liabilities are recorded in non-current income taxes payable as payment is not expected within one year.

STOCK-BASED COMPENSATION PLANS | We recognize compensation expense for all stock-based awards based on the grant-date estimated fair values, net of an estimated forfeiture rate. We use the Black-Scholes option pricing model to determine the estimated fair value for certain awards. Stock-based compensation cost for restricted stock units ("RSU"s) with time-based vesting is measured based on the closing fair market value of our common stock on the date of the grant, reduced by the present value of the estimated expected future dividends, and then multiplied by the number of RSUs granted. Stock-based compensation cost for performance-based restricted stock units ("PRSU"s) granted with market conditions is measured using a Monte Carlo simulation model on the date of grant.

The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods in our consolidated statements of comprehensive income. For stock options and RSUs, the grant-date value, less estimated pre-vest forfeitures, is expensed on a straight-line basis over the vesting period. PRSUs are expensed using a graded vesting schedule. The vesting period for stock options and RSUs is generally four years, while the vesting period for PRSUs is generally three years.

FOREIGN CURRENCY REMEASUREMENT | The U.S. dollar is the functional currency for all of our foreign subsidiaries. The monetary assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at the exchange rate in effect at the balance sheet date. Revenue, expenses, gains or losses are remeasured at the average exchange rate for the period. Non-monetary assets and liabilities are reflected at historical exchange rates. The resultant remeasurement gains or losses are included in Interest income and other in the consolidated statements of comprehensive income. Such gains or losses are insignificant for all periods presented.

RESEARCH AND DEVELOPMENT EXPENSE | Research and development ("R&D") expense includes costs for compensation and benefits, development masks, prototype wafers, and depreciation and amortization. Research and development costs are charged to expense as incurred.

ADVERTISING EXPENSES | We expense advertising costs as incurred. Advertising expenses were $6.6 million, $7.4 million and $5.8 million in 2013, 2012 and 2011, respectively.

INCOME PER SHARE | We compute basic income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the treasury stock method to determine the dilutive effect of outstanding stock option shares, RSUs (including PRSUs), and employee stock purchase plan (“ESPP”) shares. Our application of the treasury stock method includes as assumed proceeds the average unamortized stock-based compensation expense for the period and the impact of the pro forma deferred tax benefit or cost associated with stock-based compensation expense.

RECENT ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This standard requires an entity to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, similar tax loss or a tax credit carryforward exists, with limited exceptions. This

standard is effective for fiscal years beginning on or after December 15, 2013, and for interim periods within those fiscal years. We are currently assessing the potential impact of ASU No. 2013-11 on our consolidated financial statements.

In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” This standard requires entities to present information about reclassification adjustments from accumulated other comprehensive income in the annual financial statements in a single note or on the face of the financial statements. Public companies will also have to provide this information in their interim financial statements. The new requirements are effective as of the beginning of a fiscal year that begins after December 15, 2012 and interim and annual periods thereafter. We early adopted this guidance in our fiscal year 2012 and it did not have a material impact on our consolidated financial statements.

Note 3: Acquisitions

During the year ended December 31, 2013, we completed two acquisitions (collectively the "2013 Acquisitions") qualifying as business combinations in exchange for aggregate net cash consideration of $145.3 million, net of cash acquired. Substantially all of the consideration was allocated to Goodwill and Acquisition-related intangible assets, net. For information on the goodwill arising from the 2013 Acquisitions, see Note 4: Goodwill and for information on the classification of intangible assets, see Note 5: Acquisition-Related Intangible Assets, Net. In connection with one of these acquisitions, we assumed debt of $22.0 million, which was paid off in full immediately following the closing of the acquisition. We have no outstanding debt as of December 31, 2013 relating to the 2013 Acquisitions. These 2013 Acquisitions, both individually and in the aggregate, were not significant to our consolidated results of operations. As of December 31, 2013, we had not yet finalized the valuation of the deferred tax assets in connection with these 2013 Acquisitions. The finalization of these amounts is not expected to have a material effect on our consolidated financial position.

In December 2010, we completed one acquisition (the "2010 Acquisition") qualifying as a business combination in exchange for cash consideration of $8.0 million, net of cash acquired. Substantially all of the consideration was allocated to Goodwill and Acquisition-related intangible assets, net. For information on the goodwill arising from the 2010 Acquisition, see Note 4: Goodwill and for information on the classification of intangible assets, see Note 5: Acquisition-Related Intangible Assets, Net. In connection with the 2010 Acquisition, we were required to pay future installments of $7.5 million to the company's former shareholder over a four-year period ending December 2014, contingent upon the continued employment of this individual by Altera. Approximately $1.9 million was recognized as compensation expense in our consolidated statements of comprehensive income for each of the years ended December 31, 2013, 2012 and 2011.

Note 4: Goodwill

Goodwill activity was as follows:




(In thousands)	2013
Beginning Balance	$	2,329
Additions due to acquisitions	71,639
Ending Balance	$	73,968

During the fourth quarter of 2013, we revised our estimate of goodwill acquired for one of our 2013 Acquisitions to reflect our updated assessment of our ability to utilize acquired net operating loss carryforwards. Utilization of the net operating loss carryforwards acquired may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and similar state provisions. During the fourth quarter of 2013, we performed an Internal Revenue Code Section 382 study on the historical net operating loss carryforwards of the acquired entity as of the acquisition date. As a result, we revised our purchase price allocation, which resulted in a $17.3 million increase in our deferred tax asset balance for these historical net operating loss carryforwards with a corresponding decrease to Goodwill.

Goodwill is tested for impairment annually during the fourth quarter unless a triggering event would require an expedited analysis. In 2013, as the majority of our goodwill balance resulted from the 2013 Acquisitions, we performed a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In assessing the qualitative factors, we considered the impact of these key factors: change in industry and competitive environment, market capitalization, stock price, earnings multiples, changes in forecasted operating results and comparing actual results to projections, gross margin and cash flow from operating activities. As such, it was not necessary to perform the two-step goodwill impairment test at this time. Based on the impairment review performed during the fourth quarter of fiscal 2013, there was no impairment of Goodwill in fiscal 2013. Unless there are indicators of impairment, our next impairment review for Goodwill will be performed and completed in the fourth quarter of fiscal 2014. To date, no impairment indicators have been identified.

Note 5: Acquisition-Related Intangible Assets, Net

Acquisition-related intangible assets, net were as follows:

Total acquisition-related intangible assets, net	$	7,310	$	(2,436	)	$	4,874

In-process research & development ("IPR&D") assets represent the fair value of incomplete research and development projects that had not reached technological feasibility as of the date of acquisition. In 2013, we capitalized IPR&D of $28.1 million related to the 2013 Acquisitions. Initially, these assets are classified as indefinite-lived intangible assets that are not subject to amortization. IPR&D assets related to projects that have been completed are transfered to the developed technology intangible asset to begin amortization, while IPR&D assets related to abandoned projects are impaired and expensed to research and development expense in the consolidated statements of comprehensive income. Subsequent to the completion of the 2013 Acquisitions, we reclassified $17.7 million of IPR&D costs to developed technology upon finalization of one of the projects. No projects were abandoned. The remaining IPR&D projects that make up the intangible asset balance as of December 31, 2013 are expected to be completed in early 2014.

Based on the carrying value of acquisition-related intangible assets, net as of December 31, 2013, the annual amortization expense for acquisition-related intangible assets, net is expected to be as follows:



Fiscal Year	Amortization Expense

We have made certain cost method investments of approximately $12.4 million. These investments are included within Other assets, net in our consolidated balance sheets. The investments are in privately held companies in which we have less than a 20% interest and no significant influence over the investee's operations. We report our cost method investments at cost, except when investments are found to be more than temporarily impaired after an impairment review. Factors considered during an impairment review include the investee’s revenue and earnings trends relative to predefined milestones and overall business prospects, the investee's ability to stay in business such as the investee's liquidity and debt ratios, and overall general market conditions in the investee's industry. Investments are considered impaired when the fair value is below the investment’s adjusted cost basis, and the impairment will be charged to the consolidated statements of comprehensive income. We performed such a review as of December 31, 2013 and determined that no impairment existed.

The adjusted cost and estimated fair value of marketable debt securities (corporate debt securities, municipal bonds, U.S. and foreign government securities, and U.S. treasury securities) as of December 31, 2013, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties.



	December 31, 2013
(In thousands)	Adjusted Cost		Estimated Fair Value
Due in one year or less	$	175,584	$	175,671
Due after one year through five years	1,723,067		1,695,066
	$	1,898,651	$	1,870,737

As of December 31, 2013, we had 137 or $1.6 billion out of our total available-for-sale securities investment portfolio that were in a continuous unrealized loss position for less than 12 months with a gross unrealized loss of $28.4 million. As of December 31,

2012, we had 91 or $118.7 million out of our total available-for-sale securities portfolio that were in a continuous unrealized loss position for less than 12 months with a gross unrealized loss of $0.1 million.

We concluded that the declines in market value of our available-for-sale securities investment portfolio were temporary in nature and did not consider any of our investments to be other-than-temporarily impaired. In accordance with our investment policy, we place investments in highly-rated securities with high credit quality issuers, and limit the amount of credit exposure to any one issuer. We evaluate securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and our intent and ability to hold the investment in order to allow for an anticipated recovery in fair value. Furthermore, the aggregate of individual unrealized losses that had been outstanding for twelve months or less was not significant as of December 31, 2013 and December 31, 2012. We neither intend to sell these investments nor conclude that it is more-likely-than-not that we will have to sell them until recovery of their carrying values. We also believe that we will be able to collect both principal and interest amounts due to us at maturity, given the high credit quality of these investments.

Note 7: Accounts Receivable, Net and Significant Customers

Account receivable, net was comprised of the following:



(In thousands)	December 31, 2013			December 31, 2012

Gross accounts receivable	$	483,628		$	324,260
Allowance for doubtful accounts	(500		)	(500		)
Allowance for sales returns	(96		)	(52		)
Accounts receivable, net	$	483,032		$	323,708

We determine the allowance requirement, on an account by account basis, by calculating an estimated financial risk for each OEM customer or distributor and taking into account other available information that indicates that receivable balances may not be fully collectible. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered.

We sell our products to OEMs and to electronic components distributors who resell these products to OEMs, or their subcontract manufacturers. Net sales by customer type and net sales to significant customers were as follows:



(Percentage of Net Sales)	2013		2012		2011

Sales to distributors	77	%	71	%	73	%
Sales to OEMs	23	%	29	%	27	%

Significant Distributors⁽¹⁾:
Arrow Electronics, Inc. (“Arrow”)	41	%	40	%	39	%
Macnica, Inc. (“Macnica”)	23	%	21	%	21	%


(1)	Except as presented above, no other distributor accounted for greater than 10% of our net sales for 2013, 2012 or 2011.

One OEM accounted for 11% of our net sales in 2013, 16% in 2012 and 13% in 2011. No other individual OEM accounted for more than 10% of our net sales for 2013, 2012 or 2011.

As of December 31, 2013, accounts receivable from Arrow and Macnica individually accounted for approximately 26% and 55%, respectively, of our total accounts receivable. As of December 31, 2012, accounts receivable from Arrow and Macnica individually accounted for approximately 30% and 47%, respectively, of our total accounts receivable. No other distributor or OEM accounted for more than 10% of our accounts receivable as of December 31, 2013 or 2012.

Depreciation and amortization expense as presented in our consolidated statements of cash flows includes the above amounts, together with amortization expense on our non-acquisition related intangible assets.

Note 10: Deferred Income and Allowances on Sales to Distributors

Deferred income and allowances on sales to distributors was comprised of the following components:



(In thousands)	December 31, 2013			December 31, 2012

Deferred revenue on shipments to distributors	$	512,872		$	363,641
Deferred cost of sales on shipments to distributors	(33,809		)	(28,101		)
Deferred income on shipments to distributors	479,063			335,540
Other deferred revenue ⁽¹⁾	8,683			10,453
Total	$	487,746		$	345,993


(1)	Principally represents revenue deferred on our maintenance contracts, software and intellectual property licenses.

The Deferred income and allowances on sales to distributor activity was as follows:



(In thousands)	2013			2012

Balance at beginning of period	$	345,993		$	279,876
Deferred revenue recognized upon shipment to distributors	5,870,096			5,517,540
Deferred costs of sales recognized upon shipments to distributors	(269,969		)	(238,256		)
Revenue recognized upon sell-through to end customers	(1,055,137		)	(1,023,465		)
Costs of sales recognized upon sell-through to end customers	260,326			237,703
Earned distributor price concessions ⁽¹⁾	(4,575,430		)	(4,345,473		)

(Decrease)/ increase in other deferred revenue	(75		)	645
Balance at end of period	$	487,746		$	345,993


(1)	Average aggregate price concessions typically range from 70% to 85% of our list price on an annual basis, depending upon the composition of our sales, volumes, and factors associated with the timing of shipments to distributors.

We sell the majority of our products to distributors worldwide at a list price. However, distributors resell our products to end customers at a very broad range of individually negotiated prices based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. The majority of our distributors' sales to their customers are priced at a discount from our list price. Under these circumstances, we remit back to the distributor a portion of its original purchase price after the resale transaction is completed, and we validate the distributor's resale information, including end customer, device, quantity and price, against the distributor price concession that we have approved in advance. To receive a price concession, distributors must submit the price concession claims to us for approval within 60 days of the resale of the product to an end customer. It is our practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced.

Note 11: Accumulated Other Comprehensive (Loss)/ Income

The following table presents the components of, and the changes in, accumulated other comprehensive (loss)/ income, net of tax:

Note 12: Commitments and Contingencies

OPERATING LEASE COMMITMENTS | We lease facilities and equipment under non-cancelable lease agreements expiring at various times, as presented below. The facility leases generally require us to pay property taxes, insurance, maintenance, and repair costs. Total rental expense under all operating leases was $10.1 million in 2013, $10.6 million in 2012 and $8.1 million in 2011, respectively. We have the option to extend or renew most of our leases, which may increase the future minimum lease commitments. Future minimum lease payments under all non-cancelable operating lease obligations as of December 31, 2013 are as follows:



Year	Operating
	(In thousands)
2014	$	8,187
2015	5,228
2016	3,400
2017	2,967
2018	2,509
2019 and thereafter	6,742
Total	$	29,033

PURCHASE OBLIGATIONS | We depend entirely upon subcontractors to manufacture our silicon wafers and provide assembly and test services. Due to lengthy subcontractor lead times, we must order these materials and services from these subcontractors well in advance, and we are obligated to pay for the materials and services once they are completed. As of December 31, 2013, we had approximately $158.2 million of outstanding purchase commitments to such subcontractors. We expect to receive and pay for these materials and services over the next six months.

OTHER COMMITMENTS | In addition to operating lease obligations, we enter into a variety of agreements and financial commitments in the normal course of business. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments pursuant to such agreements have not been material. We believe that any future payments required pursuant to such agreements would not be material to our financial condition or results of operations.

LEGAL PROCEEDINGS | On December 8, 2010, Intellectual Ventures I LLC and Intellectual Ventures II LLC (“Intellectual Ventures”) filed a lawsuit in the United States District Court for the District of Delaware against Altera, Microsemi Corporation, and Lattice Semiconductor Corporation alleging that Altera infringes five patents. The complaint requests unspecified monetary damages including enhanced damages for willful infringement. In February 2011, Intellectual Ventures filed a First Amended Complaint adding Xilinx, Inc. as a defendant. In March 2011, Altera answered the complaint and asserted counterclaims against Intellectual Ventures for non-infringement and invalidity of the asserted patents. The defendants filed motions in the District of Delaware to transfer the case to the United States District Court for the Northern District of California and to stay the action pending re-examination proceedings in the United States Patent and Trademark Office. Intellectual Ventures opposed the motions. In January 2012, the United States District Court for the District of Delaware denied the defendants' motion to transfer the case to the Northern District of California, and in February 2012, the court denied the defendants' motion to stay. Three of the four defendants, including Altera, filed a writ of mandamus in the Court of Appeals for the Federal Circuit requesting that the case be transferred to the Northern District of California. In July 2012, the Court of Appeals for the Federal Circuit denied the writ of mandamus. In January 2013, Intellectual Ventures and Microsemi announced a settlement agreement, which included a dismissal of all claims against Microsemi. In March 2013, Intellectual Ventures and Lattice announced a settlement agreement, which included a dismissal of all claims against Lattice. In December 2013, Intellectual Ventures and Altera entered into a settlement agreement, which included a dismissal of all Intellectual Ventures’ claims against Altera and a dismissal of all Altera’s counterclaims against Intellectual Ventures. The resolution of this case did not have a material adverse impact on our consolidated results of operations.

We file income tax returns with the Internal Revenue Service (“IRS”) and in various U.S. states and foreign jurisdictions. On December 8, 2011 and January 23, 2012, the IRS issued Statutory Notices of Deficiency (the “Notices”) determining, respectively, additional taxes for 2002 through 2004 of $19.8 million and additional taxes for 2005 through 2007 of $21.4 million, excluding interest. The IRS’s determinations relate primarily to inter-company transactions, computational adjustments to the R&D credit and reductions to the benefits of tax credit carry backs and carry forwards. We deposited $18.0 million as a cash bond with the IRS in 2008, and converted this amount to tax payments in March 2012. On March 6, 2012 and April 20, 2012, we filed petitions challenging the two Notices respectively, in the U.S. Tax Court. The petitions request redetermination of the deficiencies produced by the IRS’s adjustments. The IRS has filed responses to our petitions, in which the IRS conceded the R&D credit adjustment for 2004. The Tax Court has consolidated the two cases and a judge has been assigned. The federal statute of limitations for the 2002 and 2003 tax years has expired, and the ongoing Tax Court litigation concerns only the 2004 through 2007 years.

summary judgment process, both sides filed briefs on May 28, 2013, July 25, 2013 and September 9, 2013. We expect to present additional legal arguments related to certain affirmative adjustments raised by Altera in the litigation. The parties filed a Joint Status Report addressing these affirmative adjustments with the Tax Court on February 5, 2014. We believe we have made adequate tax payments or accrued adequate amounts for our tax liabilities for 2004 through 2007 and that the outcome of the above matters will not have a material adverse effect on our consolidated operating results or financial position.

Note 13: Income per Share

A reconciliation of basic and diluted income per share is presented below:



(In thousands, except per share amounts)	2013		2012		2011

Basic:

Net income	$	440,065	$	556,807	$	770,711
Basic weighted shares outstanding	320,195		320,830		321,892
Net income per share	$	1.37	$	1.74	$	2.39

Diluted:

Net income	$	440,065	$	556,807	$	770,711

Weighted shares outstanding	320,195		320,830		321,892
Effect of dilutive securities:
Stock options, employee stock purchase plan shares, and restricted stock unit shares	2,823		3,667		5,714

Diluted weighted shares outstanding	323,018		324,497		327,606

Net income per share	$	1.36	$	1.72	$	2.35

In applying the treasury stock method, we excluded 2.0 million stock option shares and RSUs (including PRSUs) for 2013 because their effect was anti-dilutive. While these stock option shares and restricted stock units are currently anti-dilutive, they could be dilutive in the future. Anti-dilutive stock option shares totaled 1.8 million for each of 2012 and 2011. All restricted stock units outstanding as of December 31, 2012 and December 31, 2011 were included in our treasury stock method calculation.

Note 14: Stockholders' Equity

COMMON STOCK REPURCHASES | We repurchase shares under our stock purchase program announced on July 15, 1996, which has no specified expiration. No existing repurchase plans or programs have expired, nor have we decided to terminate any repurchase plans or programs prior to expiration. On August 28, 2013, we announced that our board of directors increased the share repurchase program authorization by an additional 30.0 million shares. Combined with the board’s previous authorization, there is a total of 233.0 million shares authorized for repurchase with approximately 36.8 million shares remaining for further repurchases under our stock repurchase program as of December 31, 2013. Since the inception of the stock purchase program through December 31, 2013, we have repurchased a total of 196.2 million shares of our common stock for an aggregate cost of $4.3 billion. All shares were retired upon acquisition and have been recorded as a reduction of Common stock, Capital in excess of par value and Retained Earnings, as applicable.

Common stock repurchase activity was as follows:



(In millions, except per share amounts)	2013		2012

Shares repurchased	6.2		6.9

Cost of shares repurchased	$	201.1	$	229.1
Average price per share	$	32.33	$	33.10

Note 15: Stock-Based Compensation

Our stock-based compensation plans include the 2005 Equity Incentive Plan (the “2005 Plan”) and the 1987 Employee Stock Purchase Plan (“ESPP”).

2005 EQUITY INCENTIVE PLAN | Our equity incentive program is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. The 2005 Plan provides stock-based incentive compensation (“awards”) to both our eligible employees and non-employee directors. Awards that may be granted under the 2005 Plan include non-qualified and incentive stock options, RSUs, PRSUs, restricted stock awards, stock appreciation rights, and stock bonus awards. To date, awards granted under the 2005 Plan consist of stock options, RSUs and PRSUs. The majority of stock-based awards granted under the 2005 Plan vest over four years. Stock options granted under the 2005 Plan have a maximum contractual term of ten years. As of December 31, 2013, the 2005 Plan had a total of 28.1 million shares reserved for future issuance, of which 18.8 million shares were available for future grants.

Historically, we used equity awards in the form of stock options as one of the means for recruiting and retaining highly skilled talent. RSUs and PRSUs are now the most frequently issued type of long-term equity-based award for eligible employees.

We have issued PRSUs to a certain group of senior executives with vesting that is contingent on both market performance and continued service ("market-based PRSUs"). For market-based PRSUs issued in 2012 and 2013, the number of shares of Altera stock to be received at vesting will range from 0% to 200% of the target amount based on the percentage by which our total shareholder return ("TSR") exceeds or falls below the Philadelphia Semiconductor Index ("SOX") TSR during a 3-year measurement period. We estimate the fair value of market-based PRSUs using a Monte Carlo simulation model on the date of grant. The model incorporates assumptions for the risk-free interest rate, Altera and SOX price volatility, the correlation between Altera and the SOX index, and dividend yields. Compensation expense is recognized ratably over the 3-year measurement period.

1987 EMPLOYEE STOCK PURCHASE PLAN | Our ESPP has two consecutive, overlapping twelve-month offering periods, with a new period commencing on the first trading day on or after May 1 and November 1 of each year and terminating on the last trading day on or before April 30 and October 31. Each twelve-month offering period generally includes two six-month purchase periods. The purchase price at which shares are sold under the ESPP is 85% of the lower of the fair market value of a share of our common stock on (1) the first day of the offering period, or (2) the last trading day of the purchase period. If the fair market value at the end of any purchase period is less than the fair market value at the beginning of the offering period, each participant is automatically withdrawn from the current offering period following the purchase of shares on the purchase date and is automatically re-enrolled in the immediately following offering period.

As of December 31, 2013, 3.1 million shares were available for future issuance under the ESPP. Sales under the ESPP were 0.8 million shares of common stock at an average price of $26.88 per share for 2013, 0.7 million shares of common stock at an average price of $27.90 per share for 2012, and 0.7 million shares of common stock at an average price of $26.12 per share for 2011.

VALUATION AND EXPENSE INFORMATION | Our stock-based compensation expense included in the consolidated statements of comprehensive income was as follows:



(In thousands)	2013			2012			2011

Cost of sales	$	1,932		$	1,872		$	1,655
Research and development expense	42,515			41,652			36,410
Selling, general, and administrative expense	52,177			50,062			44,685
Pre-tax stock-based compensation expense	96,624			93,586			82,750
Income tax benefit	(25,432		)	(23,998		)	(20,278		)
Net stock-based compensation expense	$	71,192		$	69,588		$	62,472

No stock-based compensation was capitalized during any period presented above. As of December 31, 2013, unrecognized stock-based compensation cost related to outstanding unvested stock options, RSUs, PRSUs and ESPP shares that are expected to vest was approximately $156.6 million. This unrecognized stock-based compensation cost is expected to be recognized over a weighted average period of approximately 2.3 years. To the extent the actual forfeiture rate is different from our estimate, stock-based compensation related to these awards will be different from our expectations.

We settle employee stock option exercises, ESPP purchases, RSUs and PRSUs vesting with newly issued common shares.

The assumptions used to estimate the fair value of the ESPP shares, and the stock options, RSUs and PRSUs granted under the 2005 Plan were as follows:

In connection with one of our 2013 Acquisitions, we assumed the acquired company's stock option plans for purposes of all unvested employee stock options that had been granted as of the acquisition date. We converted these unvested options to Altera shares and issued 55,931 shares of Altera stock options with a vesting period equal to the remaining vesting period of the assumed grants as of the acquisition date. These stock options are not included in the table above as the options were granted under a stock option plan other than the 2005 Plan, and the options were granted with a vesting period and certain Black-Scholes option pricing model assumptions that differ from the other non-acquisition related stock options granted during the year. The weighted average grant date fair value of these options is $24.42 per share. As of December 31, 2013, there are no shares reserved for future issuance under this stock plan.

On May 6, 2013 and July 30, 2012, we granted 262,647 and 66,489 market-based PRSUs, respectively, to a group of senior executives. As of December 31, 2013, the majority of these market-based PRSUs are still outstanding, and no market-based PRSUs have vested. For market-based PRSU grants made on May 6, 2013 and July 30, 2012, the weighted average grant date fair value was $33.03 and $41.18, respectively.

For stock options, the expected term represents the weighted average period from the date of grant to exercise, cancellation, or expiration. For ESPP shares, the expected term represents the average term from the first day of the offering period to the purchase date.

Our expected stock price volatility assumption for stock options is estimated using a combination of implied volatility for publicly traded options on our stock with a term of one year or more and our historical stock price volatility. Our expected stock price volatility assumption for ESPP shares is estimated using a combination of implied volatility for publicly traded options on our stock with a term of six months and our historical stock price volatility.

The interest rate used to value stock options and ESPP shares approximates the risk-free interest rate of a zero-coupon Treasury bond on the date of grant with a maturity date that approximates the expected term of the award.

In addition, we apply an expected forfeiture rate when amortizing stock-based compensation expense.

A summary of activity for our RSUs and PRSUs for 2013 and information regarding RSUs and PRSUs outstanding and expected to vest as of December 31, 2013 is as follows:

(1)	For those stock options with an exercise price below the closing price per share on December 31, 2013, aggregate intrinsic value represents the difference between the exercise price and the closing price per share of our common stock on December 31, 2013, multiplied by the number of stock options outstanding, exercisable, or vested and expected to vest as of December 31, 2013.

For 2013, 2012 and 2011, 1.8 million, 1.7 million and 4.8 million non-qualified stock option shares were exercised, respectively. The total intrinsic value of stock options exercised for 2013, 2012 and 2011 was $24.0 million, $30.6 million and $97.7 million, respectively. The aggregate intrinsic value represents the difference between the exercise price and the selling price received by option holders upon the exercise of stock options during the period. The total cash received from employees as a result of employee stock option exercises during 2013, 2012 and 2011 was $37.6 million, $31.2 million and $102.3 million, respectively.

The total fair value of options vested and expensed during 2013, 2012 and 2011 was $5.3 million, $4.9 million and $4.7 million, respectively.

The American Taxpayer Relief Act of 2012, which was enacted on January 2, 2013, extends the federal R&D tax credit retroactively for two years from January 1, 2012 through December 31, 2013. The federal R&D tax credit has not been extended beyond 2013. As of December 31, 2013, we had $6.9 million of federal R&D tax credit carryforwards. The federal R&D tax credit carryforwards will begin to expire in the year 2024. We also had $24.5 million of California R&D tax credit carryforwards. The California R&D tax credits can be carried forward indefinitely; however, we have provided a full valuation allowance for deferred tax assets related to the California R&D tax credits that are not expected to be realized.

As of December 31, 2013, we had $9.2 million and $24.6 million of U.S. federal and foreign net operating loss carryforwards, respectively, to offset our future taxable income. The U.S. federal net operating loss carryfowards were from one of our 2013 Acquisitions and will begin to expire in the year 2034, if not utilized. The foreign net operating loss carryforwards were from one

of our 2013 Acquisitions and can be carried forward indefinitely. We expect both the U.S. federal and foreign net operating loss carryforwards to be fully realizable in the future.

Under the provisions of Section 382 of the Internal Revenue Code, a change of control may impose an annual limitation on the amount of the Company's net operating loss and tax credit carryforwards that can be used to reduce future tax liabilities. As a result of the acquired tax attributes, our tax attributes are subject to an annual limitation of approximately $0.9 million per year for federal purposes.

The valuation allowance of $24.5 million as of December 31, 2013 primarily relates to a California law change providing the option to elect the single sales factor apportionment method to attribute taxable income to California for tax years beginning on or after January 1, 2011. The single sales method became mandatory for tax years beginning on or after January 1, 2013. We expect that the income subject to tax in California will be lower than under prior tax law and therefore realization of our California deferred tax assets is no longer more likely than not to occur.

The provisions related to the tax accounting for stock-based compensation prohibit the recognition of a deferred tax asset for an excess benefit that has not yet been realized. As a result, we will only recognize an excess benefit from stock-based compensation in additional paid-in-capital if an incremental tax benefit is realized after all other tax attributes currently available to us have been utilized. In addition, we have elected to account for the indirect benefits of stock-based compensation such as the R&D tax credit through the consolidated statements of comprehensive income.

The items accounting for the difference between income taxes computed at the federal statutory rate and income tax expense are as follows:

We file income tax returns with the IRS and in various U.S. states and foreign jurisdictions. On December 8, 2011 and January 23, 2012, the IRS issued Statutory Notices of Deficiency (the “Notices”) determining that additional taxes of $19.8 million for 2002 through 2004 and an additional $21.4 million were due for 2005 through 2007, excluding interest. The IRS’s determinations relate primarily to inter-company transactions, computational adjustments to the R&D credit, and reductions to the benefits of tax credit carry backs and carry forwards. We deposited $18.0 million as a cash bond with the IRS in 2008 and converted this amount to tax payments in March 2012. On March 6, 2012 and April 20, 2012, we filed petitions challenging the two Notices in the U.S. Tax Court. The petitions request redetermination of the deficiencies produced by the IRS’s adjustments. The IRS has filed responses to our petitions, in which the IRS conceded the R&D credit adjustment for 2004. The Tax Court has consolidated the two cases and a judge has been assigned. The federal statute of limitations for the 2002 and 2003 tax years has expired, and the ongoing Tax Court litigation concerns only the 2004 through 2007 years.

On January 31, 2013, the IRS conceded one of the adjustments at issue in the litigation for the 2004 through 2007 tax years. The conceded adjustment related to certain inter-company services transactions. The concession only impacted our 2007 tax year. As a result of this concession, we recognized a tax and interest benefit of $6.8 million in 2013 due to the release of certain tax reserves. Altera and the IRS have filed cross motions for partial summary judgment on the largest adjustment still at issue, which is related to the treatment of stock-based compensation in an inter-company cost-sharing transaction. As part of the partial motion for summary judgment process, both sides filed briefs on May 28, 2013, July 25, 2013 and September 9, 2013. We expect to present additional legal arguments related to certain affirmative adjustments raised by Altera in the litigation. The parties filed a Joint Status Report addressing these affirmative adjustments with the Tax Court on February 5, 2014. We believe we have made adequate tax payments or accrued adequate amounts for our tax liabilities for 2004 through 2007 and that the outcome of the above matters will not have a material adverse effect on our consolidated operating results or financial position.

During the third quarter of 2013, we reversed $30.3 million of liabilities for uncertain tax positions upon the expiration of foreign and domestic statutes of limitation and related interest mostly relating to the expiration of federal statute of limitations for the 2008 and 2009 tax years. The resulting decrease in our effective tax rate in the third quarter of 2013 was substantially offset by $27.7 million of tax accrued on foreign dividends.

Other significant jurisdictions in which we are or may be subject to examination for fiscal years 2002 forward include China (including Hong Kong), Denmark, Ireland, Malaysia, Japan, Canada, United Kingdom and the state of California. We believe we have made adequate tax payments and/or accrued adequate amounts such that the outcome of these audits will have no material adverse effect on our consolidated operating results. Due to the potential resolution of various tax examinations, and the expiration of various statutes of limitations, it is possible that our gross unrecognized tax benefits may change within the next twelve months. However, given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.

The aggregate changes in the balance of gross unrecognized tax benefits for 2013, 2012 and 2011 were as follows:



(In millions)	2013			2012			2011
Balance at beginning of year	$	296.4		$	306.5		$	263.3
Additions based on tax positions related to the current year	67.3			45.1			51.1
Additions for tax positions of prior years	2.7			4.8			5.7
Reductions for tax positions of prior years	(42.3		)	(60.0		)	(13.6		)
Balance at end of year	$	324.1		$	296.4		$	306.5

As of December 31, 2013 and December 31, 2012, the total amount of unrecognized tax benefit that, if recognized, would impact the effective tax rate was $301.3 million and $275.9 million, respectively. These amounts are presented net of federal benefits for the deduction of interest and other deductible items.

Estimated interest and penalties related to unrecognized tax benefits are recognized in tax expense. We recognized a net expense of $0.1 million in 2013. The net expense of $0.1 million is primarily due to $3.9 million in interest and penalty expenses related to general unrecognized tax benefits, offset by the reversal of $3.8 million of interest and penalties associated with the reversal of uncertain tax positions resulting from the IRS conceding an adjustment for certain 2007 inter-company transactions in our 2004 through 2007 litigation, changes in estimates for certain foreign jurisdictions, and the expiration of foreign and domestic statutes of limitation. We recognized a net benefit of $6.0 million and a net expense of $4.8 million in 2012 and 2011, respectively. The balance of accrued and unpaid interest and penalties was $48.8 million as of December 31, 2013 and 2012.

In connection with one of our acquisitions in 2013, we are indemnified by the selling company for certain potential tax obligations arising prior to the acquisition. We have recognized a tax indemnification receivable of $6.5 million in Other assets, net in our consolidated balance sheets. We do not expect any significant effect on earnings or cash flows related to these potential tax obligations.

U.S. and foreign components of income before income taxes were:

Income before income taxes	$	470,828	$	591,917	$	848,992

Aggregate unremitted earnings of our foreign subsidiaries were $3.1 billion as of December 31, 2013. These earnings, which reflect full provisions for foreign income taxes, are indefinitely invested in foreign operations. If these earnings were remitted to our U.S. entities, they would be subject to domestic and/or foreign taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

Note 17: Segment and Geographic Information

We operate in a single industry segment comprised of the design, development, manufacture, and sale of PLDs and related software design tools. Our sales by major geographic area are based on the geographic location of the OEMs or the distributors who have purchased our products. The geographic locations of our distributors may be different from the geographic locations of our end customers. Long-lived assets include property and equipment, net, which were based on the physical location of the asset as of the end of each fiscal year.

Note 18: Employee Benefits Plans

ALTERA CORPORATION SAVINGS AND RETIREMENT PLAN | We provide a retirement savings option to our eligible U.S. employees through the Altera Corporation Savings and Retirement Plan (the "401(k) Plan”). As allowed under Section 401(k) of the Internal Revenue Code, the 401(k) Plan allows tax deferred salary deductions for eligible employees. Our Retirement Plans Committee administers the 401(k) Plan. Participants in the 401(k) Plan may make salary deferrals of up to 75% of their eligible compensation (when combining regular and catch-up contributions), limited by the maximum dollar amount allowed by the Internal Revenue Code. For every dollar deferred under the 401(k) Plan, we make a matching contribution equal to 100% of the salary deferred per pay period with a maximum of $4,500 per participant in each of 2013, 2012 and 2011. All matching contributions are immediately vested.

Participants who reach the age of fifty before the close of the 401(k) Plan year may be eligible to make catch-up salary deferral contributions, limited by the maximum dollar amount allowed by the Internal Revenue Code. Catch-up contributions are not eligible for matching contributions. Total matching contributions to the 401(k) Plan were $6.2 million, $5.8 million, and $5.4 million in 2013, 2012 and 2011, respectively, and were expensed as incurred.

ALTERA CORPORATION NON-QUALIFIED DEFERRED COMPENSATION PLAN | We allow our U.S.-based officers and director-level employees to defer a portion of their compensation under the Altera Corporation Non-Qualified Deferred Compensation Plan (“NQDC Plan”). Our Retirement Plans Committee administers the NQDC Plan. As of December 31, 2013, there were 122 participants in the NQDC Plan who self-direct their investments in the NQDC Plan, subject to certain limitations. In the event we become insolvent, the NQDC Plan assets are subject to the claims of our general creditors. Since the inception of the NQDC Plan, we have not made any contributions to the NQDC Plan and we have no commitments to do so in the future. There are no NQDC Plan provisions that provide for any guarantees or minimum return on investments. NQDC Plan participants are prohibited from investing NQDC Plan contributions in Altera common stock. The balance of the NQDC Plan assets and related obligations was $83.2 million and $77.4 million as of December 31, 2013 and December 31, 2012, respectively.

The following tables summarize the fair value of our deferred compensation plan assets by significant investment category:

(1) Included in Deferred compensation plan - marketable securities and Deferred compensation plan - restricted cash equivalents in the accompanying consolidated balance sheets as of December 31, 2013 and December 31, 2012.

Investment income or loss earned by the NQDC Plan is recorded as (Gain) loss on deferred compensation plan securities in our consolidated statements of comprehensive income. The investment (gain) loss also represents an (increase) decrease in the future payout to participants and is recorded as Compensation expense (benefit) - deferred compensation plan in our consolidated statements of comprehensive income. Compensation expense (benefit) associated with our NQDC Plan obligations is offset by (gain) loss from related securities. The net effect of investment income or loss and related compensation expense or benefit has no impact on our income before income taxes, net income, or cash balances.

(Gain) loss on deferred compensation plan securities from our NQDC plan assets for 2013, 2012 and 2011 was comprised of the following:

OTHER EMPLOYEE BENEFIT PLANS We offer participation in a Service Award Program (“SAP”) to U.S. employees below the Vice President level and to non-U.S. employees. The SAP provides employees with one to four weeks of additional paid vacation upon their achievement of five, ten, fifteen, twenty and twenty-five year service anniversaries.

Note 19: Credit Facility and Long-Term Debt

Credit Facility

On June 29, 2012, we entered into a five-year $250 million unsecured revolving credit facility (the "Facility"). Under certain circumstances, upon our request and with the consent of the lenders, the commitments under the Facility may be increased up to an additional $250 million. Borrowings under the Facility will bear interest at a base rate determined in accordance with the Facility, plus an applicable margin based upon the debt rating of our non-credit enhanced, senior unsecured long-term debt. In addition, we are obligated to pay a quarterly commitment fee, payable in arrears, based on the available commitments. This facility fee varies and is also determined based on our debt rating. The terms of the Facility require compliance with certain financial and non-financial covenants, which we have satisfied as of December 31, 2013. As of December 31, 2013, we have not borrowed any funds under the Facility.

Long-Term Debt

The carrying values and associated effective interest rates for our Long-term debt was comprised of the following:



(In thousands, except rates)	Effective Interest Rate	December 31, 2013		December 31, 2012

2013 Senior Notes due November 15, 2018 at 2.50%	2.71%	$	596,920	$	—
2013 Senior Notes due November 15, 2023 at 4.10%	4.29%	395,056		—
2012 Senior Notes due May 15, 2017 at 1.75%	1.94%	499,490		500,000
Total long-term debt		$	1,491,466	$	500,000

On October 29, 2013, we issued $600 million aggregate principal amount of 2.50% senior notes (the “2.50% Notes”) and $400 million aggregate principal amount of 4.10% senior notes (the “4.10% Notes”) for general corporate purposes, including stock repurchases. We received net proceeds of $991.8 million, after deduction of a discount of $8.2 million, and we capitalized direct debt issuance costs of $5.5 million from issuance of the 2.5% Notes and the 4.10% Notes.

In 2012, we issued $500 million aggregate principal amount of 1.75% senior notes (the "1.75% Notes") to repay our outstanding credit facility. We received net proceeds of $499.2 million, after deduction of a discount of $0.8 million, and we capitalized direct debt issuance costs of $3.7 million from issuance of the 1.75% Notes.

All three of our senior notes (the “Notes”) pay a fixed rate of interest semiannually on May 15 and November 15 of each year. The Notes are governed by a base and supplemental indenture between Altera and U.S. Bank National Association, as trustee. The Notes are unsecured and unsubordinated obligations, ranking equally in right of payment to all of our existing and future unsecured and unsubordinated indebtedness and senior in right of payment to any of our future indebtedness that is expressly subordinated to the Notes. We may redeem the Notes, in whole or in part, at any time and from time to time for cash at the redemption prices described in the indentures.

The direct debt issuance costs associated with the Notes are recorded in Other assets, net in our consolidated balance sheets and are being amortized to Interest expense in our consolidated statements of comprehensive income over the contractual term using the effective interest method.

The carrying values of the Notes are reflected in our consolidated balance sheets as follows:



	2.50% Notes					4.10% Notes					1.75% Notes

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Altera Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of comprehensive income, of stockholders' equity and of cash flows, present fairly, in all material respects, the financial position of Altera Corporation and its subsidiaries at December 31, 2013 and December 31, 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in the reports we file or submit pursuant to the Securities Exchange Act of 1934 (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management, with the participation of the Chief Executive Officer and Chief Financial Officer, has performed an evaluation of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2013, our disclosure controls and procedures were effective.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is the process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that:


(i)	pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of assets;


(ii)	provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with the authorization of our management and directors; and


(iii)	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with established policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2013. In making this assessment, it used the criteria based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (1992). Based on the results of this assessment, management (including our chief executive officer and our chief financial officer) has concluded that, as of December 31, 2013, our internal control over financial reporting was effective.

The effectiveness of our internal control over financial reporting as of December 31, 2013 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a - 15(f) and 15(d) - 15(f) under the Exchange Act) that occurred during the fourth quarter of fiscal 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
